DD I love you too.
By the way. It's crazy to read the best book ever and then not watch the movie because it's R rated.
Anyway I think american movie ratings are crazy too. There can be a lot of violence. But if there is a few F words it's R rated. My favourite movie "The Big Lebowsky" has in every sentence the F word. In Europe the rating is 12+, in america it's R rated.
