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.
