I remember back in 1980 seeing ads and coming attractions for a film called "Airplane". Nobody really famous in it, but the ads made it appear that it would probably be a mildly amusing film, and a decent way to get some A/C on a hot afternoon. I was shocked then when I saw the film and laughed my ass off through the whole thing.
Similarly, I had no reason to think, based on the ads I'd seen, and the mediocre nature of most recent comedy films, to expect much from "The Hangover". I was surprised that Kip, the woman I have been dating, said I HAD to see it, and would see it for the third time with me. She said it was hilarious, and she was not lying.
If you haven't seen it yet, go see it NOW!! It is not a movie you chuckle thru, it is a movie you laugh really hard at for the whole time. Several times I tried to take a sip of coke at after a long hard laugh, only to nearly do a spit take when the next big laugh came unexpectedly. The beauty is you never see anything coming.
"The Hangover" is going to be a cult classic, a film that people will be watching and laughing at 30 years from now. Don't wait 30 years to see it. Go today!
