Alf: This review actually comes as a surprise. We recently watched this movie at home, it was my second time. I had originally watched it in the theater with friends, but Beth hadn't gone with us. The reason I say that it was a "surprise" was because I had no idea that it could possibly be in the imdb top 250. At the time that I had watched it, I thought the movie was funny and entertaining, but even then knew that it wasn't "timeless." Apparently, people are starting to realize this. At the time we had printed the list of Top 250, The Hangover was at 175, now it's no longer on the list. We said at the beginning that we were doing the Top 250 at the time, and this is why. The list keeps changing, there'd be no way to keep up with the changes from week-to-week.
Anyway, the movie does have funny parts in it, but most of the writing is unfortunately only good for laughs the first time. That's the problem with a lot of comedies (for me). You really need to have some great dialog for a comedy to be funny over and over, if the whole movie consists of slapstick-type humor, it doesn't really do it for me after the first time. In short, I'd say that people should watch the movie if they're never seen it before, since it does provide a few good laughs and Zach Galifianakis steals the show. Also, resist the temptation to watch it again, it's always better in your memory.
