Query: Really is a great movie.

The title tells the story. Wedding Crashers; Owen Wilson and Vince Vaughn are wedding crashers who ... crash weddings to have sex with girls. Eventually, they both meet girls at a wedding and end up going to a family cottage. ( A huge one. ) Anyways, the story is somewhat slow and boring at times, but basically this is a laugh fest. Will Ferrell comes in near the end of the movie and every line he says is funny as hell. There is no reason why this movie should get less than 4 stars, it is hilarious.Note: I have the unrated version and it is no different the the theatrical version... I don't get it.
