I loved the movie. Some funny, some gross, some crass, and some lines that will live in movie infamy (Im the dude, playing the dude, disguised as another dude)
I originally watched it in the theater the day it came out. I have never laughed as loud at the movies than I did the first time I watched it. I had problems catching my breath in some scenes. What's strange, is I just watched it on blu-ray last week, and while I still love the movie, it wasn't 1/4 as funny. Maybe because I knew what was comming, or something.
What amazed me the most, was the all-star cast. Nick Nolte, Jack Black, Tom Cruise, Matthew Mcconohay (sp?), Downey, and Toby Maguire, who nobody has mentioned yet.
