Parents need to know that there are some frightening situations, such as shrunken adults running from cockroaches, and that children run wild when they think their parents are away for the weekend. But the movie also offers positive lessons about standing up for yourself and respecting your parents.
Positive messages:There are good, easily digestible lessons here: help each other; don't let bullies take advantage of you; and appreciate your parents, even if they're smaller than you are -- much smaller.
