I Love You, Man - 9/10 - I'm a big fan of Paul Rudd, so this was an instant favorite of mine. It actually gets funnier with multiple viewings, because much like something like Anchorman, you pick out the more ridiculous finer points of the dialogue and characters the second and third time around. What I like is that all of the characters seem like real people, not the over-the-top caricatures of personality types that you see in most comedies.
The Hangover - 4/10 - I know people that think this movie is a laugh riot, but to me it's barely funny at all. The characters aren't very interesting or likeable, and the plot seems to set itself up for a hilarious payoff, but that payoff never materializes. Supposedly this movie is really quotable, but the quotes are all just characters saying stuff in a stupid voice instead of saying anything clever, IMHO. Only about two or three scenes made me chuckle...for the rest of the movie I was surfing the web on my iPhone. I'll never understand the appeal of this movie.
