At 4% on the Tomatometer, The Roommate is a pretty insipid Single White Female retread, but it has its incidental pleasures - not least Billy Zane's campy performance as Professor Roberts, a skeevy, ethically-challenged fashion design instructor. He's a bad teacher for a bunch of reasons. First, he violates his own policy by letting Sara (Minka Kelly) talk her way into his class, even though it's full. Then he crudely hits on her. Finally, he's forced to take a leave of absence after Sara's evil roommate Rebecca (Leighton Meester) records him acting in a generally sketchy manner. Looks like he won't be getting tenure.
