This movie is rated R. In fact, this is so R on the R scale that Jennifer and I debated elements of it afterward that it might need to be NC-17....almost.
But we both liked it. A lot.
But if you don't watch R rated movies, this is definitely not one of those 'gray area' movies that you might see for cinematic or 'artistic' value.
The Hangover is not, for example, by any stretch of the imagination, Shcindler's List.
What it is is great fun. There have been 'wacky hijinks' or 'boys will be boys' comedy style movies for as long as there have been movies, but this movie dials the concept up to 11. Basic plot synopsis is that four friends get drunk in Las Vegas for a bachelor party and wake up in a hotel room that shows the consequences of the previous night. And they remember none of it.
So they spend the entire movie unraveling the clues of what happened in order to get themselves out of a dire situation. It is a comedy, and a good one. I suspect it is one that will stand the test of time, though it is probably not what I would call 'iconic.'
