Spoiler alert ahead.
Great animated movie. Recommended for older kids. Scary, funny, good story.
Loses one star for the ending though. After the Monster House trashes the neighborhood as it chases the boys, the girl, and the old man, there is no trace of the mass destruction after the house is blown up. The two boys go trick or treating in a perfectly intact neighborhood that was moments before a wreck. Oh well. Still highly recommended.
