The John Hughes touch, a baby, lots of slapstick/physical comedy, 3 likable stooges for the bad guys and an affably implausible story.....all makes for a great kids movie.
I watched half of this with my kids to make sure it was appropriate, and had no problem with the content. The bad guys are bad but not evil. They get hit with boards, paint cans fall on their head, etc....but the baby always comes out unscathed. It's all silly fun, nobody really gets hurt, and the kids loved it.
