After watching snippets of "Ice Age 3" on a flight back to L.A., we thought our girls might like the first "Ice Age," not realizing how much violence there is in the movie. Should've checked Common Sense first! Definite moments of peril, a saber-tooth lion getting stabbed by falling ice, etc. make this a big NO for anyone younger than fourth grade, in my opinion. Too bad, because the squirrel is hilarious!
