My family has been watching this movie around Christmas for years! The movie itself is simply the hilarious story of a family trying to put together a "good old-fashioned family Christmas", and all of the crazy mishaps that come their way. Most of the humor is appropriate and funny for children as young as five years old, that being said however, some of the language is not appropriate for preteens and younger. There are some mild sexual references, however they go waaayyy over the head of very young children, and there is no major sexual scenes that cannot be watched by anyone twelve years old. The violence is mostly in the form of funny accidents; a pet cat gets electrocuted, Clark Griswold falls of a latter, etc. While this movie may seem to have some very flawed characters, the message they send about the holidays is a good one, especially in our modern age. Clark goes out of his way to make Christmas special for his niece and nephew who's parents can't afford presents, Clark's boss admits to people being more important than saving a buck, and of course there's a happy family ending. Overall, I would have to highly recommend this movie for anyone with children 12 and over, it is a great family classic.
