I try to highlight those few things in popular culture that re-enforce Christian value.
Disney's new movie Mars Needs Moms does just that.
In the movie, Milo's mom is kidnapped by Martians who use the brains of human mothers to create better child-care robots — necessary because their society has cast off males entirely, leaving the females too busy to be mothers. Milo stows away on the kidnappers' ship and, with the help of a man who was once in Milo's shoes, tries to rescue his mother before it's too late.
It's not a great movie, but it is a good movie, and the kids will enjoy it. More importantly, though, the movie will show them that mothers and fathers are important.
There are a couple of unfortunate moments of potty humor (one during the closing credit montage), but overall it's pretty clean with mild violence. I think there was one mild swear word. Visually, it was very attractive (we saw it in 2D). And you should expect to get all verklempt during the climax.
I give it 3 1/2 out of 5 stars. If you're going to take your kids to one of the cartoons that are out now, this is the one to see.
