Jason Lee does his best to bring fun to a silly situation, but the movie just fails to make a connect. Perhaps because Julia Stiles character seems awkward as the conniving and sexy soon to be cousin-in-law. Maybe it is because she and Selma Blair's characters should have been cast the opposite way. (Selma Blair seems more conniving than Julia would be).Either way this movie is yet another Hollywood trivialization of a possibly real world situation (that being getting caught with your pants out at your bachelor party not stooping your cousin), which while having promise fails to deliver.There are some laughs to be sure and the cast (even if miscast) do their best with sub grade material which doesn't transcend its raunchy topic. So instead of getting a successful raunch fest (ie Animal House or American Pie) we are left with a middle ground of part humor and part stupidity (ala Meatballs 2 or something).
