This is one of the worst movies I have ever seen.

Rating: Null/10 (5 August 2011)

"Bad Teacher" features all the most disgusting aspects of an American comedy.
It mixes obscenity and prudeness, managing to make each equally irritating and painful to watch. Very few of the jokes are funny ; most of them are stupid and obvious. There is absolutely no cleverness in this movie, be it in the writing, acting, or editing. Putting drugs in a movie does not make it funny. Usually, good films designed for an mature audience do not revolve around drugs to be funny and/or interesting ; it is merely something you mention to create an atmosphere, and it's by no means supposed to be a comic relief.
The actors are all equally bad.

Cameron Diaz is annoying, unfunny, and obnoxious in a way that wasn't planned by the film "director". - Justin Timberlake portrays a stereotypical prude-sensitive-faggy-dim- witted virgin, in order to provoke the hilarity of indoor-baseball-cap wearers from Suburbia, USA. - The Amy character is unbearable. - Jason Segel still isn't funny, and plays a retarded gym class teacher. What is funny though is how the director, knowing that mostly frat morons would enjoy his movie, has put one of them inside and made him eventually hook up with the hot girl to content his audience.

I saw this film in Paris, where I live, and I didn't hear a laugh.
