It's a love or hate, a lot of people hated it. I thought it was much better than the reviews made it out to be. As long as people go in expecting a series of totally unrelated low-brow skits I think there is enjoyment to be had. I thought it was quite funny.
Certainly it was a better movie than Sharknado.
In one skit a guy has testicles on his chin that only his date seems to notice.
In another, a home schooled kids parents are over-protective and by the end his mom wants to give him the high school experience by having him go "all the way" with her.
If you don't think you'd find that funny, skip the movie.
One of the best parts is that it has so many a list actors in it. The guy who put it together did a good job "tricking" them into this movie.
