I'm a huge Joss Whedon fan based on the Buffy and Firefly franchises, and I was a fan of the Uncanny X-Men (and spinoffs Alpha Flight and The New Mutants) back in the early-to-mid-eighties, so I suspect that I liked Whedon's take on the X-Men more than your average Whedon fan.

It should come as no surprise to any of Joss's fans that he finds a way to make the heart of the story arc be one of the not-so-powerful female characters from the X-Men universe: Kitty Pryde. Her story here is more compelling than those of the other mutants, and Whedon succeeds at giving her a bit of depth. The story covers insanely wide ground over the course of the four "volumes", and the premise is absurd (though no more than is usual for superhero comics), but it's good fun.
