there's comic book/sci-fi logic where as long as it's plausible and works in the context of the story, even silly shyt can work
and then there's fukking amnesia bullets...
instead of the systematic corrupting and erasing of his mind and memories in the comics, the movie literally says that if you shoot an adamantium skull with an adamantium bullet, that person will forget everything
it's completely and absolutely stupid to an insulting degree
plus turning Deadpool into eye-beam Baraka, Cyke & Prof X meeting here but not knowing each other in X1, the glaring error that is Will.I.Am's existence, the fact they think wolverines are wolves, etc, etc, etc...
It's just a fukking shame of a flick mostly because most the cast is great, and you can build a great film off his past (like how dope is the credits montage of Wolvy & Sabes throughout the decades?), but they ended up making a sloppy, scattered mess.
