Let's be honest, there aren't that many actually funny comedies starring women. I don't do stupid (sorry ladies) romantic comedies. Not my thing. I don't find them funny, and they are SOOOO predicable. I like just plain comedies: The Hangover, Borat, School of Rock, Talladega Nights. These are movies I almost wet my pants from laughing so hard.
I would definitely classify Bridesmaids as a comedy (not a romantic comedy) and even better, as an actually funny comedy. It's a must see! Guys will like it too, so don't worry about dragging your man along.
Also, here's a tip (it's free, take it). Don't watch the trailer! I was just about to post it on here, and it shows SOOO many of the funny parts. I HATE trailers like that. Why do they have to ruin it!?! I didn't see a trailer before hand, and now I'm glad I didn't.
