After seeing the commercial on TV, I was not at all interested. But since Mars Needs Moms comes from the makers of Monster House, and The Polar Express, I decided it wouldn't hurt to give it a try, and the animation got me. So realistic, (maybe a little too realistic at times). The overall message is a decent one, that will relate to kids of all ages. But the storyline is a little strange though. A 9 year old boy must save a parent who has been abducted by aliens. Not your every day movie plot line. Violence is a big issue; this movie is jam packed with fighting, zapping, falling, smashing, exploding, you name it. All this, and there seems to be no "breaks". So I recommend this movie for children ages 9 and up. Most kids this age are mature enough to handle heavier topics like this one, but more sensitive viewers might need second thoughts. (Do not take young children to see this movie, even because it is animation. You will regret it.)
There is also a few sad scenes, (one being very emotional near the end of the movie). Everything turns out fine in the end though. Kids who see this movie will look at their mothers differently, and learn in the end to respect not only their moms, but their whole family too.
