"Pacific Rim" three points for parents:
Violence: Giant alien monsters are fighting giant man-made robots. Yes, there is violence, but it is very much in a fantasy realm. Some hand-to-hand combat takes place, sometimes due to anger and other times for evaluation.
Gore: The alien monsters could scare smaller children, as they tend to appear from nowhere. Also, they are very large and loud. Some weapons cut into the aliens and there are alien body parts that are seen.
Language: Only a few instances of profanity occur, one after the credits.
