Breaking the fourth wall is just one of the ways that the director connects the audience into the film. This is a fully immersive film that kept me connected to the character for the whole feature. This isn't your usual superhero that is a role model to the public. Rather Deadpool is a "hero" that is so typical of people in their 20s. He makes dick jokes and is not afraid to say exactly what he thinks at any given moment. This is a great breakaway from the mentor-hero type that we get from Captain America, Wolverine, and those other somewhat boring and one-dimensional characters.
While the film continually jokes throughout the story, not all of the jokes were that great. I am definitely excited for another Deadpool movie, but I hope that they can create a more clever script. The jokes were fun, but got a bit exhausting as some of them lacked being clever. That being said, this film is exactly what it was marketed to be and I am sure Deadpool couldn't give one shit what I have to say about it.
The Bottom Line: Funny and fun, check it out for an actually good Ryan Reynolds character.
