Ice Age: Dawn of the Dinosaurs

While the first two Ice Age films were humorous character studies of unlikely prehistoric friends, the "threequel" is less compelling than its predecessors and much more about the action. Audiences already know how the main characters interact, so the focus shifts to the dangerous search for Sid and the obstacles that Manny, Diego, Ellie, and her nitwit twin "brothers" (Josh Peck, Seann William Scott) face. This works fine for Ice Age: Dawn of the Dinosaurs' 3-D scenes, but in the process the movie loses a tiny bit of the franchise's humor and heart.

The only memorable new additions are Buck (British comic actor Simon Pegg), a hermitic warrior weasel who guides the crew to Sid, and the three dinosaur babies, who can't play well with their Ice Age friends (a playground scene hilariously turns into an unlikely feast as the triplets swallow their new playmates). And arguably the best new character doesn't utter a single word: Scrat's love interest, Scratte, a winged female creature who desires that elusive acorn just as much as her beloved. Scrat and that acorn are the perfect animated example of physical comedy, and their scenes alone are worth a trip to the multiplex.
