While I found Deadpool in the comics to be rather annoying and unlikable, his film adaptation does everything right and turns him into a human being. It says a lot that some of the best scenes, besides the great jokes, are about his cancer and relationship.
Overall you can tell that this is a film by fans for fans and no soulless mass product. The action is really well directed. It is over the top and brutal but not as gory as feared. The connections to the X-Men-verse work wonderfully, too and make for some of the best gags. Certainly no masterpiece like some films of Marvel Cinematic Universe, but a massively entertaining and fun experience. Deadpool will return and that’s good news
