How vulgar is it? My wife and I aren't prudes, but there's just a limit! For instance, we turned off The 40 Year Old Virgin after about 30 minutes! Edgy is one thing (the movie Happiness, for instance), but crude/sophomoric sexual "humor" wears thin after a while.
It wasn't overly sexually vulgar, but there were some 'gross' blood and guts that were mostly satirzing the typical fair of most war movies. Most of the humor doesn't come from raunchy dialogue, and the movie was very well done. It excellently satirizes both the state of today's movie business and the cliches that exist in many war movies, while at the same time poking fun at a number of famous Vietnam films. I highly recommend it. The humor is for the most part well crafted and not stupid like many teen oriented movies.
