Snowball Earth

Shy, socially awkward mecha pilot Tetsuo spent his entire childhood fighting kaiju – the intergalactic monsters threatening life on Earth. Out in deep space at the climactic moment of the final decisive strike against humanity's gargantuan enemies, something goes horribly wrong with his mecha Yukio's new doomsday weapon, the Omnidirectional Infinity Laser. With Earth's last-ditch strategy failing spectacularly, his beloved mecha sacrificing itself to save his life, sole survivor Tetsuo hurtles back to Earth in his escape pod and, eight years later, awakes from cold sleep to find his world inexplicably frozen from pole to pole.

Snowball Earth is based on the manga series by Yuhiro Tsujitsugu. The anime series is streaming on Crunchyroll on Fridays.

Finally, a mech series that's about the pilot and not the giant robots!

Haha, I kid, I kid. I'm well aware of the fact that it's actually much rarer in the modern era for a mecha anime to be primarily about the robots. I'm actually not even sure at the end of this episode whether or not it'll be a true mecha series, considering how Tetsuo and Yukio's battle against the kaiju goes. In fact, it's a bit hard to give a rating to a premiere like this, when I have no idea what the rest of the series is going to be like.

Becoming a pilot at the age of nine hasn't exactly set Tetsuo up to be a normal teen. His only social connection is with his giant robot. On the bright side, he does get to live the dream of every person with social anxiety: hurling himself out the airlock after flubbing a normal human interaction. If I had a dollar for every time I wished I could do that, I'd be a richer woman than I am today. Maybe not much richer, but I'd probably be able to afford a nicer apartment. Our poor boy is not well-adjusted, and as much as he professes to desire friends, he seems to have developed a quiet acceptance of his isolation from his peer group.

But did he have to sacrifice his normalcy for fighting what appears to be an invasion of axolotls with googly eyes attached to their faces? Tetsuo and Yukio are animated primarily with CG and look great – it's truly wild how far things have come in the last few years – but the kaiju just look awful. They're impossible to take seriously, even when they are actively overwhelming and murdering the supporting cast. That's only one episode in a mild case of tonal whiplash that permeates the episode, and there were moments where I had no idea whether I was supposed to take what was happening seriously. It undercut the moments of pathos and left me chuckling uneasily at what were supposed to be jokes.

Still, I'm curious about what lies ahead for Tetsuo. He's entering into a world unlike any he's ever known, and I want to see him grow and learn through his social anxiety. If nothing else, I might keep watching just for that opening and closing….

Here is the question to ask yourself before you decide whether to watch Snowball Earth dubbed or subbed: do you need to read the onscreen text? Because even with closed captions on, the dub will not allow you to do so. That became the only reason I ended up sticking with the sub as the episode went on, because it annoyed me to a possibly unreasonable degree. I liked Griffin Burns and Takuto Yoshinaga equally as Tetsuo, and I think I may have preferred Alejandro Saab slightly over Daisuke Hirakawa as Yukio, but if there's text, I need to read it. End of story.

Speaking of story, this is a bleak start to Snowball Earth's. That's perhaps not surprising: it's a war story when it opens, and those need to be bleak to get the point across. Kaiju have come from space to attack the earth, and the only hope is a mech called Snowman. Snowman has been designed to be both self-aware and to blow himself up, which isn't a great combination. He's only saved when his inventor's nine-year-old son climbs in the cockpit and expertly pilots the machine…and when a nine-year-old is sent into battle for ten years, you know things are desperate. (Or that the adults in this world have a very odd sense of child safety.) We know from the title that the kaiju are unlikely to be defeated in a way that's compatible with human life, and sure enough, when Tetsuo returns after losing quite literally everyone he's known for the past decade, the situation looks grim.

That's a large part of the reason I couldn't get into the first volume of the manga, and here things aren't helped by some truly deranged looking CG kaiju who have a sort of bug-eyed fetal lizard look to them. The animation in general feels off, although we've all certainly seen worse examples; it's still too smooth in its textures and has a slightly weightless quality that has nothing to do with a lack of gravity. Despite the emotionally manipulative plot, the circumstances precipitating Tetsuo's return to earth are effectively upsetting; they just don't quite fit with Tetsuo's awkwardness and inability to say anything without making a fool of himself.

I do think there's a decent post-apocalyptic story here, and it very much feels like this episode was getting the setup out of the way. We now know Tetsuo's backstory and what he hopes for going forward. Even if this episode wasn't great, I think it'll be worth a second to see how the main story gets off the ground.

This is a show suffering from some major tonal dissonance—and while I'm sure it's intentional, I'm not entirely sure how I feel about it. Switching from Testuo's humorous, socially awkward self-deprecations to everyone he knows and works with being brutally killed is one heck of a shift—especially when it goes right back to the comedy soon after.

What's interesting about this episode is that it's technically all setup—a prologue rather than the start of the main story. But even more interesting is the fact that, despite it being all set up, we still have no idea what's going on. Why did the kaiju come to Earth? Why is Earth now in an ice age? Has it really only been eight years?

But what really interests me are the more subtle mysteries. Like why did the laser fail to fire? Why did the ship's power and all defences fail soon after? Was it due to faulty design (which seems insane as you'd expect everything to have been tested hundreds of times) or was it sabotage? And if the latter, who did it and why? These are all good mysteries that easily work to propel the plot forward beyond Tetsuo's personal goal to gain 100 friends.

And speaking of that goal, that feels like the weakest aspect of the show in my eyes despite being the most central. Going from super shy kid to socially awkward adult due to fighting giant monsters works as a character trait but building the show's plot and humor around it feels a bit much.

In the end, I'm not sure how I feel about Snowball Earth. This first episode was perfectly watchable and it does it's job of setting up the story, however, I didn't really feel myself connecting with Tetsuo as he's more caricature than character at this point. I'll have to think long and hard to figure out if I want to continue watching this one or not.

Maybe it's because I've been playing a hell of a lot of Earth Defense Force lately, but Snowball Earth's introduction hit me with the perfect amount of Stupid Monster Nonsense Energy™. I am, of course, a lifelong devotee to Stupid Monster Nonsense, but decades of fanatical kaiju consumption has developed in me a somewhat snobbish palette. It's not enough for an anime to throw a bunch of random and larger-than-usual beasties at the screen for some anonymous hero to punch with his big robot fists. I need a story that understands that big, stupid monster battles need to be matched with big, stupid human emotions—and the presentation of these elements must strike an ideal balance of childish sincerity and the honed, meticulous obsessiveness of a master craftsperson. This is especially true in the medium of animation. Cheap and janky live-action kaiju possess their own brand of timeless charm, and video games like the EDF franchise balance their knowingly cheap stories and graphics with addictive gameplay. Animation only works when it works, though. A cartoon cannot stumble into greatness on a foundation of mediocrity.

I was sold on Snowball Earth before the opening credits began to roll. For one, I love the way we are introduced to the stupid-looking but nonetheless imposing intergalactic kaiju that decimate the earth. The show instantly reassures us by demonstrating its skill with the 3D animation that Studio KAI is using to tell this ridiculous story, and it earns bonus points for cribbing from the Shin Godzilla school of giving terrifying monsters of mass destruction doofy little googly-eyes. By the time the narrator is intoning about the young Japanese schoolboy who will become known to all as “The Saviour”, it is clear that Snowball Earth will have its tongue planted firmly in its cheek as it weaves this tale, even as its animators take the job of bringing the story to life incredibly seriously. That's the stuff that kickass kaiju anime are made of.

Snowball Earth's premiere continues to impress by establishing a fun, futuristic setting that feels like something ripped straight out of a late-80s or early-90s sci-fi anime, except with a modern coat of paint to make the action go down smoothly. Tetsuo also makes for an endearing dork of a protagonist, serving as a punishing reminder for all of the mediocre light novel anime out there that a protagonist can suffer from anxiety and social-awkwardness without being an insufferable bore. You want this guy to make a real, non-robot friend just as much as you want him to smash up all of the space-lizards that are going to wipe out humanity.

So, yeah, I loved Snowball Earth's first chapter, and I can't wait to see more in the coming weeks. However, while I'm here, I need to make a humble request of Crunchyroll, who is streaming the series here in the U.S. Now, I assumed this would be obvious for a company like the big CR, but somebody in charge apparently needs to be reminded that a show with a simulcast English dub needs to have its Japanese text translated on-screen, too. The English dub for Snowball Earth is pretty good, capturing that all important blend of sincerity, sweetness, and camp. I couldn't enjoy it for long, though, since I have the Japanese reading comprehension of a five-year-old—and all of the on-screen text only has subtitles on the Japanese audio track. Hopefully this issue will be fixed post-haste, so as many people as possible can enjoy the fun of Snowball Earth for themselves.
