Okay for, say, a 10-year-old who's seen Back to the Future, all the Star Wars movies, all the Pirates of the Caribbean movies, and the recent Godzilla? Language is an issue (he knows the words, he's been to Walmart, but he's not allowed to use them), but mostly want to avoid sexual stuff and overly bloody violence.
The violence is bloodless( I Can not recall any blood, unless maybe some alien blood) and the sexual stuff is not really there.
