I'm not a big cartoon person but there are a few cartoon movies that I'll watch. I went to see this w/my whole family and that includes 6 kids ranging from 3-9. We all LOVED this movie!! I loved this movie! (If someone says their 2 or 3 year old lost interest it's most likely because young children have a very short attention span.) I know everyone has different tastes for movies but I have to say it takes alot for me to laugh out loud at any movie and I did many times watching Monsters vs Aliens. It was definately worth the $ spent on the ticket and popcorn! LOVED IT!!! Can you tell?
