Name me one movie that was based off a novel, comic book, video game, or TV program that is as good as the original series in every way and stayed completely faithful to the story with no omissions.
Well Mr. and Mrs. Smith seemed exactly liked the book, which the book was short, okay, and had no ending. I can say the same exact thing for the film. Well it sounds like you way more knowledged on X-Men than I am. There's also like charlie said it's more than what the fans are complaining about. I good deal of those critics have never seen the show.
