I felt like the whole concept of Bad Teacher was stupid. However, I did laugh at parts. This has more of a stupid humor. The story line wasn't very good at all. This is only worth a rental and not a purchase! I just felt like the whole movie was off for some reason, that the characters and story were just there for the sake of being there with no real purpose. I don't really know how to describe it. I almost felt by the end of the movie that nothing was really achieved and we were at the beginning again. Overall, two stars for at least keeping me semi interested with barely decent humor.
