To say this first, my opinion on this movie is mostly subjective.
For me it seems as if the movie is split into two different directions.
On one hand it has the sexual humor and bloody violence of a movie for adults, on the other hand the storytelling and jokes are extremely childish and weak. This makes the movie kind of tiring to watch because the movie can't combine mature content and comedic parts like other movies are able to do.
The acting is average at best.
