“Roommate Wanted” (** out of four) was a noisy, predictable melodrama about two roommates (Alexa PenaVega and Spencer Grammer)- one an ambitious student, the other a rich slut- whose differences come to a head which leads to them both trying to kill each other. Both girls look great but a better script and more original storyline should have been wanted by all involved. Bridget Fonda and Jennifer Jason Leigh did this similar story and much better nearly 25 years ago in “Single White Female”.
