I enjoyed it but I thought a few things....
First healing factor much to slow, and the only reason it was done was for a joke that could've happened earlier. Next it was wrong that the girl still liked him. That's nothing like the comic and could ruin the character. He should be more fucked up. All of the early comics with him were good because he is a combination of being screwed up and tries to make it comedic. Here's the difference, he doesn't necessarily make you laugh because he's fairly demented. We needed more of the passive aggressive comedy with him. And he never stops talking. Also when he's upset he has a torture box room he goes in or puts people in.
He also wins fights with anyone you can think of by out smarting them in strange ways, often after getting torn to pieces first to inspire confidence.
The X-men rejected him, always have, because he's a demented for hire killer that is a big enough of a megalomaniac that he'll save the world because it sounds fun to be a hero.


They did this in the movie, essentially.

He seriously loved trying to out hero heroes.
