My kids loved, loved, loved this movie! They watched it two times in row on friday night, and then another time the next morning. They are ages 3, 5, 7 and 9.
This movie is waaay better than you would expect. There's an actual story line with bad guys hunting for jewels. There were many scenes that were "exciting" to my kids. The level of humor was perfect for them (bad guys being pelted with snowballs by penguins). If you've got young kids under 12, I highly recommend this for them. They will thank you!
