If you read the comics, know the characters, and hate when writers more familiar with writing big budget Michael Bay action schlock decide they don't need to read the comics to write a "killer movie, dude", then prepare to hate this movie.
Everything seems to be going along fine, taking small liberties, until Wolverine walks away in slow motion from an exploding helicopter. Thats when the shark has been jumped and the writers must have given up and started throwing darts at characters to include and reasons for them being there.
