kidsinmind is a fantastic site (if you don't care about
   spoilers) if you want to know the naughty bits / interesting
   bits of a movie. Lots of good info about the tone of the movie,
   fear factor and stuff. I used to poo-poo the site years ago as
   being ridiculous, counting up curse words and things. But
   whenever I'd be curious about a movie, I found myself going to
   it more and more frequently. They actually give a fascinating
   perspective on movies that you don't see elsewhere and I think
   they try their best to remain "just the facts, mom" as it were.
