"Extract" works well with a majority of its audience. Reason is clear...the cast is very good, story is not boring or cheap; comedy is neither vulgar nor downright stupid; at ~90 minutes it doesn't bore anyone and it has a happy ending!!! Cast wise, a very good job. Jason Bateman plays the sex-deprived businessman role very well. Mila Kunis looks hot throughout the movie and that's exactly what her character was all about. Ben Affleck has a small but a very funny role. JK Simmons hardly does anything wrong about his acting. Others are good in their context.
The best thing about "Extract" is that the humor is maintained throughout the movie. It's neither cheap vulgar comedy nor downright stupid comedy. The comedy is an elaborate mix of these two poles and that's why this movie is like able. All the characters seem to be performing on a high wire and carry themselves very naturally. There is never a dull moment taking into account the short running time. Besides, the soundtrack is so cool. Really lovely songs.
Overall, "Extract" is a good movie. Can't say it's a very good movie, but still I can guarantee few smiles for sure.
My Verdict: 7/10
