Haha, I think Mutant X started out strong, and I actually found it very interesting...at the time, I found it most interesting out of all the X-books. But towards the end...I don't even know...I don't even remember what happened. But unlike Ultimate X-Men, Mutant X took really unique takes on all of the characters. Bobby unable to touch. Storm didn't heal from being bitten by Dracula. Rogue permanently absorbing Colossus' power, thus killing him. Polaris being Magneto's daughter - oh wait, that happened in normal continuity...hmm...
