The whole thing with Wolverine and Sabertooth being brothers bothered me a lot at first, but if you look at the movies as an alternate universe, it's not so bad. And the adamantium bullet to the head explains why he doesn't recognize Sabertooth in X1.

My biggest gripe was with Deadpool. I never read any of the comics, so I don't really consider myself a comic nerd, but I do know the basics of a lot of the characters. In the beginning, this Deadpool was pretty close to the comic version. He was a smartass and used swords. The only things missing were the red costume and the breaking of the fourth wall. But when he comes back in the end of the movie, he has adamantium swords in his arms which make him look like a knock off of Baraka from Mortal Kombat, is silent due to his mouth being sewn shut by Stryker (which is alluded to in the beginning when he says "If you didn't have that mouth you'd be a great soldier.") and has the teleporting and optic blast powers of John Wraith and Scott Summers, respectively. Completely fucking ridiculous.

And young Xavier might as well have been completely CG, he looked so fake.

- The first altenate scene you see Weapon XI's hand reaching out from the rubble of the nuclear complex to touch his severed head, where upon the head comes to life and makes a brief hushing sound before the scene fades to black; breaking the fourth wall like the Deadpool comics.

- The second alternate ending shows Weapon XI going to grab his head, similar to the first ending, but then a man in a black coat steps on the arm, stopping Weapon XI, and picks up the head. The camera then turns around and it is Wade Wilson (Ryan Reynolds) who then asks "What the hell are you supposed to be?"

- The third alternate scene shows Wolverine drinking at a bar in Japan. The female bartender asks if he is drinking to forget; Wolverine replies that he's drinking to remember.
