jason lee do his best to bring fun to a silly situation and but the movie just fail to make a connect . perhaps because julia stile character seem awkward a the conniving and sexy soon to be cousin in law . maybe it be because she and selma blair character should have be cast the opposite way . ( selma blair seem more connive than julia would be ) . either way this movie be yet another hollywood trivialization of a possibly real world situation ( that be get catch with your pant out at your bachelor party not stoop your cousin ) and which while have promise fail to deliver . there be some laugh to be sure and the cast ( even if miscast ) do their best with sub grade material which doesn not transcend it raunchy topic . so instead of get a successful raunch fest ( ie animal house or american pie ) we be leave with a middle ground of part humor and part stupidity ( ala meatballs 2 or something ) .
