The movie was pure shit.
They destroyed the storyline, along with mixing in random characters just so fanboys would go "Ooooo cool!"
for one, Gambit was never even involved in the Weapon X program, and never had anything to do with the Island.
Wolverine never had bone claws (up until recent comics, which were only made to lead up to the movie)
Scott Summers was never a captive on the island.
And countless other fuckups that they did to the storyline made me pretty upset.
Normally, even with a fucked up view, sometimes the movie can still be a good movie, which unfortunately wasn't the case here.
