Apparently, though, a lot of other people do, because I have seen some truly caustic reviews of this movie.
So let me preface this (to ward off suggestions that I am a frat boy with a low IQ)with the following:
I'm female and have a doctorate.
This movie was freaking hilarious. I laughed start to finish on this one. It's Old School-scale hilarity. It's crude, it's obnoxious, and it's not headed for the Oscars, it's just headed to a place on my admittedly small shelf of DVDs, to join my collection of go-to movies to smooth over a rough day at work. It will get you out of your bad mood, that's for sure.
The actors had great chemistry, the scenes were outlandish (although looking back on it, their adventures, while outrageous, were actually fairly tame. Want to see a Las Vegas bachelor party gone seriously awry? Watch "Very Bad Things". And yeah, I liked that one, too.), and I laughed just as hard at my second viewing as I did my first. And Heather Graham? Now there is an underappreciated actress. Why doesn't she get more roles? She was great as the good-hearted stripper. Ken Jeong's first scene had me crying with laughter. That guy is funny in everything he is in.
Also, the scene with the baby that so many complained of? It's just a guy acting stupid with a fully clothed baby. It reminded me of something my little brother and one of his nitwit friends might have done when I brought my infant son over. Is he pretending to molest the baby? No. Is he pretending the baby is molesting him? No. It's not child abuse, it's not sexual abuse, and to suggest it is demeans real victims of such abuse, so please get over yourself.
Caveat: My kid is 18, so I would let him watch this movie, but you probably don't want to watch it WITH your kids, regardless of their ages. It might be a little awkward.
