J.N.
Go to kidsinmind.com. My pediatrician recommended this site to me several years ago and I have used it a lot. It will give you exact reasons why it is rated what it is rated. It lists nudity, sexual content, violence, and language, ranks each one (0-10 with 0 being none, I believe) and describes what kind (mild profanity, "escatorial references," strong language; partial or full, front or rear nudity, even if "nipple shape can be seen through swimsuit"; etc).
It is a bit of a "spoiler" for parents because of how well it describes everything, but it's worth it, IMO.
Edit: oh, yeah, I think it also lists drug uses/reference
