You have to give credit to James Asmus: He bizarrely makes you feel sympathy for Sebastion Shaw. Despite the fact he was one of the X-Men's greatest threats, Asmus manages to make you feel sorry for him. After getting his entire memory wiped, he now has been betrayed by someone he trusted and was tricked into killing dozens of innocents.
Besides that, the art is fairly gritty, and I love the ending. As usual, some of the characters are fairly annoying, but some impress, including Zero's dry wit and Shaw's bizarre rationality.
