Like the previous movies in this series our main characters return, lacking only Oz, who I personally feel is the least interesting of the original guys anyway.  Stifler has become by far the most important character in the series if for nothing other than humor.  Luckily he plays a huge role in all the going's on.  The basic overview without ruining it for those who haven't watched is that Jim and Michelle are getting married after graduation.  Both of these characters have numerous problems with just everyday life so one can imagine a wedding would be disastrous, and of course it is.  Stifler manages to mess everything up continuously through the movie in his attempt to score.  One could guess he is feeling a little down with his current career (Coach of the football team).  I have two personal favorite scenes (and friends seem to agree).  The dance scene is hilarious (you'll have to watch the movie to understand).  The second coolest scene still makes me a little queasy.  It involves dog poop and Stifler eating (and no, he didn't think it was anything else).  To say much more could potentially ruin the movie for others so I'll end with saying that this movie Rocks!!!  If you liked the original and second installment you'll love this finale to the trilogy.
