I'm shocked by the negative reviews for this

I get it that some snobs would have an issue with this going away from its more simple TV series roots, but as a standalone movie this is fantastic. I think anyone who had a decent teenage/young-adulthood can relate to this movie to some extent and the charisma of the characters alone makes this movie extremely fun to watch.

Any suggestions for something similar? Other than the obvious Inbetweeners 2.
