Jim & Michelle's wedding plans turn interesting when Stifler gets involved.
At the time American Wedding came out it appeared to be the perfect wrap-up to the series and all good things came in threes. Jim had proposed to Michelle (through a somewhat typically embarrassing moment in a fancy restaurant) and the American Pie characters (those who remained) were now involved with the wedding preparations. Cue the formula that ran successfully in the previous two instalments.
For whatever reason though, this outing appears to be the Stifler show with his character taking much of centre stage throughout. It's really about his quest to get with Michelle's sister and putting on a false persona to do so. I guess it works and there probably is only so much that Jim's character could do if he were to carry the film.
What results is lots of crude humour, more bare skin and a scene involving dog poo that's best forgotten (and easily avoidable in a real world situation surely!)
American Wedding brought the trilogy to a decent end - until someone reopened the book with the Reunion.
