Not a perfect movie, but much better than some reviews suggest.

Rating: 8/10 (6 November 2011)

Let's face it, the reason many people call Bad Teacher the "worst movie ever shot" is not rational, it doesn't have to do with the movie itself in any way. From the reviews I have read on here the main problem seems to be the moral values in this film leading many "oh so shocked" viewers to give bad reviews, question people's sanity for producing this movie and hate everything about it - whether they admit it's the reason they dislike it or pretend to hate everything about an objectively well crafted film. But this movie is not supposed to teach anyone life lessons, it's not supposed to have some big, moral message about how to live your life in a good way. This is a film for adults. And films for adults do not have to follow certain morals because an adult is expected to judge morals on their own without needing guidelines. An adult can enjoy movies with main characters doing things they would never find acceptable because it's not about agreeing with the character's actions.
Normally, I would rate this film 6 stars, but I rated it 8 to keep some of the irrational reviews on here from bringing the score down too far. It has solid jokes, a mostly good cast, OK direction but also some really bad moments and the main character goes completely out of character towards the end to achieve the usual Hollywood "we need a kiss! FAST!!!" Happy Ending, but overall a good comedy I would watch again with a great performance from Cameron Diaz.
