Although I thought Monster House was pretty scary for kids, the many many kids in my theater did not seem to be that frightened, and I heard lots of "I loved it" after the movie had ended.
In Monster House, DJ (Mitchell Musso's voice) realizes the house across the street is alive, and scary.
The house's only inhabitant is curmudgeon Mr. Nebbercracker (Steve Buscemi's voice).
The grumpy goth babysitter Zee (voiced by Maggie Gyllenhaal) was excellent. She was edgy and funny.
As expected in a kids movie, we had no gay content, but it was cute to see DJ's mom pushing his father to show affection towards the boy, making him say "I love you." What kind of a redneck father would not say "I love you" to his son before going away for a few days?
