If you have the slightest interest in comics, the x-men specifically, animation or just good storytelling, I encourage you to watch this, especially for free.
You can also get the first three seasons from Netflix, but the wrap-up 9 episodes of the 4th season are (I think) only available from Hulu for now.
Anyway, it recasts most of the X-men as high school students, with Prof X, Beast, Storm and Wolverine as older professors.
The students on the show attend a nearby high school undercover, where the brotherhood of evil mutants (Blob, Avalanche, Rogue, Toad and Quicksilver) are their fellow students/rivals.
It does a great job of melding superheroics and teen/high school angst, along the lines of Smallville.
It's probably my favorite form of the x-men outside the comics. Yes, I like it better than the movies (though I do happen to like the movies too).
