This is easily my favorite X-Men related tv series (I don't count Astonishing X-Men, but also check that out), but this is a very loose adaption. The big plot hook, Xavier in the future communicating with the X-Men, warning them of the dystopian future to come, has never been in the comic book and other plots adapted are picked and chosen from many runs over several alternate universes (and are still loose adaptions) but this series has the voice of almost every character, in both writing and acting. Wolverine in this, while toned down, is believably wolverine. While he is more responsible than usual, he still runs off to do his own things and leaves a villain in a torture machine. While rouge antihero was odd for Cyclops (at this point: he that's essentially what he's been in the comic did the past three years), it really works, especially after his origin episode. They NAILED Emma Frost (I hear Kari Whalgren, Emma's voice actress, saying her lines when I read the comic books) and had her and Scott develop their relationship in a less messed up way than the comics. Polaris, one of the worst written characters in the comics, is interesting in both her present and future forms (minor spoiler: they are different). I am a little angry that Psylocke, one of the most powerful telepaths in the marvel universes, is referee to as an "amateur telepath", but everyone else (except Storm, who is always adapted badly) is great. It is a major shame that this was cancelled before they adapted the "age of apocalypse" universe (and after just one season!).
This show is mostly fine for kids, with a few points to discuss and some violence. The messages of teamwork, diversity, and the series's spotlight on the mutant metaphor send good messages to kids and warn them away from bigotry. All of the characters truly believe in what they're doing, including villains, and while this greyness adds interest for adults, parents should talk to kids about how that is how real life works. There is light comic book violence and a desert dystopian future, but nothing is too scary. Emma Frost, as always, wears crazy revealing clothing, and though this fits her complex character, this may be too much for young girls. This is an excellent show for the whole family, with a little caution.
