Parents need to know this is a pretty scary movie, and the last 20 minutes, in particular, take a turn for the dark. With windows like eyes and a flying carpet that unfurls tongue-like out the front door to scoop up trespassers, the house is a wonderfully alive structure. But it's creepy. You don't want your kids waking up in the middle of the night freaked out that their house is going to eat them. Most of the PG content comes from the scariness.
