Man, that sucks to hear. I guess we shouldn't be surprised that it would end up trying too hard to make it funny throughout the entire movie. So, would you suggest not seeing it in the theater?
I don't know. I did find the first half of the movie really funny. I know people who enjoyed the entire movie. For me personally I was disappointed with second half of the movie.
I'd say see it at a matinée if you want to see it in the theater.
