Friends with Benefits is a clever, just-this-side-of-painfully-hip relationship comedy that knows when to linger over a punch line and when not to break stride. A few minor speed bumps aside (filmmakers: can we can it with the musical montages, already?), it goes down extremely easy. The story in a nutshell: frustrated by the lack of viable dating options in their vicinity, two platonic friends (Mila Kunis and Justin Timberlake) decide to embark on a casual, no-strings-attached physical relationship. However, as a briefly glimpsed clip from Bob & Carol & Ted & Alice foreshadows, things don't stay simple for very long. As opposed to the standard PG-13 rom com, things get surprisingly raunchy here, but organically so, with the slight snafus and briefly major embarrassments that should ring true to most relationship veterans.
