Mostly missed opportunities to be funny.

Rating: Null/10 (26 January 2006)

As one professional critic aptly wrote (Ebert) this movie is all runway and no takeoff. It apparently is right now the most popular DVD rental, and many viewers really like it, but I found it mostly odd rather than funny. It is as if the writer and director didn't really know how to make funny situations actually funny.
As the movie opens we see the real professions of Owen Wilson (John) and Vince Vaughn (Jeremy) -- they are divorce mediators. But their real passion is the wedding season each year, where they become clever wedding crashers to pick up young attractive women who are easy prey because the wedding atmosphere softens them up. They have their approach down pat and some of their schtick is really funny.
Most of the movie focuses on their big challenge, crashing the party of Christopher Walken who plays the powerful Washington DC Secretary William Cleary. They do, and end up at his home, a retreat on the water. But things go wrong when (1) the younger, pretty, redhead daughter falls for Jeremy (she is described as a stage 5 clinger) and he can't shake her, then (2) John falls for the prettiest daughter Claire (very pretty Rachel McAdams). They are supposed to hit and run, but this particular situation forbids that. I felt that Jane Seymour was wasted as the wife of the Secretary, always horny and mildly chasing John. Also Will Ferrell had a small role which was particularly unfunny and ruined the rest of the movie for me.
SPOILERS. John and Jeremy end up falling in love with the two sisters, ending their wedding crasher hobbies.
