I'll admit that my rating system is not quite objective and is based more on how much I enjoyed the show than in its production values or whatever. I tend to give extra points to shows that make me nostalgic -Saint Seiya and Digimon are good examples of this. I also really take into account whether the show achieved what it attempted to, and whether it delivered what it promised. Some ratings are not exactly how I feel about a show, I seriously feel a "forgettable" and "memorable" rate should be available. "Mediocre" and "hilariously awful", would be fab too.

I must add that my enjoyment of this show was seriously marred by the Latino dub in which I watched it. Seriously, should be avoided at all costs. That being said, I still enjoyed the depiction of the transition to the Meiji era, how the samurai find that they've lost their place in a modern society, and the repercusions of that. And if not for anything else, the series is worth watching because Kenshin is incredibly likeable

Puella Magi Madoka Magica The Movie Part 3: Rebellion

Puella Magi Madoka Magica the Movie Part 1: Beginnings
I'm not going to rate the Madoka movies because I think my enjoyment of them was seriously obstacled by them not meeting my expectations. Unlike most anime films I've watched, there was absolutely no new content in either film (save for one scene in Part 2) and even the animation seemed copy-pasted from the anime series, to the point where I wonder if they actually reanimated anything or just edited the series and tweaked it for the big screen. The editing is superb, they manage to fit the whole story in 4 hours without losing anything that's really important, and the 1st film ends in a perfect moment, but that's about it. I hope the third part lives up with its new story to the absolute lack of novelty that these films were. But I think it would be unfair to rate them poorly since the story is amazing, the animation is amazing, the characters -save Madoka with whom I can't empathize no matter what- are amazing. It's just exactly the same as the series, and I expected at least some new or different stuff like, say the TTGL films or something.
