I have to admit that I am not a fan of Deadpool. In fact I hate him nearly as much as I hate his creator, Rob Liefeld. Basically he created Spider-Man with guns and gave him a healing factor like Wolverine. Hardly the most original character around. Spider-Man was always rooted in his own kind of reality where his Peter Parker's morality and sense of responsibility keeps him from doing all the things that Deadpool has no problem with - murder, murder and more gruesome murder. After a few deaths in the comics you just have to keep pushing the envelope to keep interest in the character alive and for me a very little bit of Deadpool goes a long way. He's boring and obvious. I so wanted this movie to fail but as it appears, surprisingly, that someone actually cared about telling a story and Ryan Reynolds found a character he could put all his energy and charm about being. His enthusiasm is infectious and is a big reason for the success of this picture.
Fortunately, the movies are the perfect place to let this kind of character roam free and express every nasty thought he has in his head. It's a solid revenge fantasy turned up to an 11 but the film remains very small in scope. This is not an overstuffed Marvel blockbuster. This style and R-rating also gives Deadpool the opportunity for black comedy by designing some of the best death scenes since Kick-Ass. I love watching guys who can heal basically beat the shit out of each other for no reason because no one is going to win if no one can get killed.
In the end, I had a good time with this violent live action comic book despite myself. The relationship between Deadpool and his favorite cabbie is a Netflix series I would watch everyday for the comedy possibilities alone as is the love story between him and Morena Baccarin.
I was very impressed with Colossus, one of my all time favorite mutants and it's great to see him in action as he's meant to be. He brings much comedy relief to all the mayhem as well and it's only as a Superhero comedy that all this works. Never take your high concept so serious, go full retard on the execution and you will find movie success. This film takes my advice to the extreme.
