I had to chuckle aloud. When the anime first started, it was like seeing a modernized, non-English version of X-men: The Animated Series, and it brought back memories of my youth. Long-running comics have a continuity problem because concepts like the Phoenix cannot be satisfactorily explained in five minutes. As a result, they alter narratives, characters, and other elements to suit their purposes and make some sense. It made sense for the X-men to travel to Japan in order to save a young mutant from Japan! And by the time the anime ended, we practically had the lineup for the Amazing X-men.
Again, quite reminiscent of the classic X-men TAS. Although it's more Western, the style is also more adult than typical anime. Especially the T and A. Reminded me quite a bit of Jim Lee's work.
How dramatic! Fit the plot rather nicely.
Whoa, I like how Wolverine and Cyclops (or, to be more scientific, Cyclopsu) would joke around. Characters were remarkably similar to those in comic books; for example, Beast the intellect, Cyclops being emo, Jean pleading to be killed, etc. Although Storm could have been better, I enjoyed how anime Storm differed from comic book Storm. She appeared quite cool. And even though I'm not usually a fan of Wolverine, I thought he was really fantastic.
This anime is really fun, and it connects to the Wolverine anime rather nicely. Marvel had a big involvement in making it, which is great, but I wish they would have invested the same kind of care in their own films.
