4.8? Geez people, loosen up!
This film had me cracking up the entire time! I watched like 3 depressing films in a row and this was meant to be a dumb comedy to get you laughing... and it did just that! It is not meant to be a deep plot or anything, its just supposed to be goofy.
So even if you said "this film is stupid"... guess what, it accomplished its goal. Life's short guys, have some fun.
