The House Bunny is nothing if not ambitious. Yes, you read that right! Upon watching the trailer, I noticed that it seems to be exploiting not one but two clichéd chick-flick premises we've seen a hundred million times. Premise one: cute, dumb-seeming blonde chick proves she's more than just a hot bod and a pretty face (what up, Legally Blonde?). Premise two: nerdy girl -- in this case, girls -- gets super-dooper makeover and turns into a sexy biatch, but learns that the boy she's been sweating loved her for her all along (nice to see you, Princess Diaries!). Those two hideously over-done plots merge when Shelly (Anna Farris) gets kicked out of the Playboy Mansion where she's been living, because at age 27, she's past her hottie expiration date. She finds herself looking for a job and a place to live, and decides that duh, the obvious solution to her woes is to become a den mother for a sorority house full of nerdy girls. (I have a bone to pick here -- in the universe of movie clichés, when have we ever seen a sorority house full of geeks? Movie sororities are populated exclusively by shallow, gum-snapping, highlights-possessing, designer label whores, thank you very much. Jeez Louise!)
