This aims for 'Legally Blonde'/'Mean Girls' status, but ends up being a throwaway, if entertaining, plea for casting directors to start taking Faris more seriously.
The flatness of humor comes from the directing and timing, rather than necessarily the dialogue or actor skill. More than once I thought to myself, "That joke totally could have worked."
The result isn't very funny, and its sexual politics are as muddled as you'd expect, but Faris is sweet and likable as the sort of wise dumbbell Judy Holliday used to play.
