I'm still passing on this series, and not because of Shun being a girl or anything, but because the whole trailer, despite having decent animation gives off the feeling that this doesn't even have the feeling of the Saint Seiya, I loved Saint Seiya for having Ancient Greek settings, fighting, what's with the fighting against the Japanese military in a desert thing? It's coming off like this series doesn't need to try to make any effort to be good because it has Saint Seiya characters/tropes; all it needs to do is show Saint Seiya stuff and people will be happy. The cloths, the familiar characters, attacks, etc. "It's all there", this anime is thinking, "Now I don't need to put any effort into making this compelling". The story looks empty and cliche, the set pieces are stuff we've seen hundreds of times before...
Here's an experiment: take all the Saint Seiya stuff from this trailer and replace it with a different, generic concept/setting like a military war one, and you'll realize that what you're left with is useless, cheap crap that no one will give a shit about, coming off like the producers are making a series they KNOW would not succeed on its own and slap on a Saint Seiya/Knights of the Zodiac label so people will watch it and it'll be better for marketers/merchandisers. Same problem I had with the first two seasons of Sailor Moon Crystal, where they thought making a piece of garbage anime, making no effort to animate nor write anything even close to a new, compelling interpretation of the manga story or new interesting versions of the characters and just slapping a label of a popular Toei Animation anime franchise on it was enough to keep me and others entertained, because they thought we were infants or had the intelligence of an infant.
