They're a bunch of goofy-dressed whiny bastards that take up too much page-space when I'm looking for scanworthy Domino stuff, mostly.
Other than that? I could probably mouth off something about representation and equality, but seeing as it was the cartoon that brought me into the X-verse to start with, I still firmly believe that the core guiding principle behind this decades-long franchise is Fighting Purple Robots. Endlessly fighting purple robots. Then, now and forever.
