As many gay men would know, Beyonce’s album I Am Sasha Fierce comes in two discs. The first has heartfelt ballads like Halo and If I Were A Boy. The second has fast fierce numbers like Single Ladies. Beyonce said she split her songs on two discs to reflect the many sides of her.

Her new film Obsessed splits her into two as well. At the start of the film she is a sweet and obedient wife, incapable of hurting a fly. By the end of the movie she is Sasha Fierce, punching her enemy in the face and smashing planks on her. You can imagine Beyonce's fans snapping their fingers and going: You go, girlfriend.

But only Beyonce's fans. For everyone else, Obsessed is more likely to draw groans and yawns than finger-snaps. Yes, it’s that bad.

Beyonce plays a good and gentle woman who loves her husband (Idris Elba from The Wire) very much until a single white female (Ali Larter of Heroes) gets the nerve to try and steal him from her. Nobody steals Beyonce’s man from her! The claws come out, the feathers fly.

Directed by Steve Shill, Obsessed is a poor copycat of films like Fatal Attraction, Crush and The Hand That Rocks The Cradle, all centering on psychotic women trying to steal another woman’s man. In those films, the characters were convincing and compelling. In Obsessed, everyone behaves in cartoonish way that defies belief. As much as we love Beyonce’s music, her role and her acting (and her saying yes to such an awful script) get a straight F.

We wouldn’t recommend this to anyone except diehard Beyonce fans.
