Just saw Four Christmases and was SO disappointed. As I've mentioned before, I first read of the concept for this film ages ago and thought it was such a brilliant idea for a Christmas movie. It had nearly unlimited comedic potential and had the promise of being a year-on Xmas classic. Well, they blew it.
Despite a great initial idea and a top cast (Robert Duval, Sissy Spacek and Jon Voight, all wasted in minor roles as the divorced parents), the film is a badly-written, lazily-directed series of cliches. There are two funny bits - Reese Witherspoon getting trapped in a jumping castle and Vince Vaughn falling off his dad's roof while trying to fix the TV aerial. Otherwise the movie bored me (and most of the audience, judging by the muted reactions) to tears.
One of the problems is that Vaughn, who is likeable and funny in small doses, was let completely off the leash in this one and is just obnoxious. Reese Witherspoon, as his supposedly adoring fiancee, could barely hide her dislike....
It just goes to show that you can start with a diamond and end up with a lump of coal.
