the olivia munn character was supper smart and had brass balls dude. what was her name. sloan something. hilarious too. check her out. i guess she just needed a better storyline.

potato face girl on the other hand was a weak-minded lunatic. she gets better by the end though.oh there's a spoiler, sorry.
