The bar for 3-D animated movies has been set high. This year alone, the skewed demonic fairy tale Coraline, the pop-up-book clever Monsters vs. Aliens, and the wondrous and heart-lifting Up make tough acts to follow. So maybe that explains why Ice Age: Dawn of the Dinosaurs has a little trouble measuring up.

Our glacier-happy regulars have been hanging out for so long now that they seem a bit jaded. Manny and Ellie (Ray Romano and Queen Latifah), the woolly mammoths, are set to have a baby, and Diego (Denis Leary), the saber-toothed tiger, is still a freelance grouch. Leave it to Sid (John Leguizamo), the lisping sloth, to discover three cuddly baby T. rexes, who lead them all to a viny green prehistoric jungle packed with dinosaurs.
