Good watch, could watch again, and can recommend.
I can recommend this, but I feel like it needs a caveat for being a "Super Hero" movie where the "Super Hero" is a drug addict. It's like one step past the line that "Hancock" danced around.
The other big caveat is that it is shot "found footage" / "fakumentary" style, he literally does 4th wall breaks to a cameraman that couldn't possibly be there unless it's like "Chronicle" where he's floating the camera, which would also be impossible in some cases. And none of it cute like in "Deadpool".
The movie itself is actually pretty entertaining, the characters are mostly funny, there is good action, and the writing is pretty nuanced with a good gradual build up in not only the story, but the character development.
