It really feels like a film made by people who care and who love the character, where the other X-Men's films feel like they are made by flipping through comic books and pointing at random characters. Or people reading the Wiki page and lacking any depth.
I'd put it as one of the 6 best comic book movies of all time. And the best part is that Cable is going to be in part 2 and that is the coolest news I've ever heard!!! Go see Deadpool! Fox did good!
