So you thought I couldn't sink any lower than to watch Talladega Nights? Oh, how little you know.
This is, of course, the sequel to Ice Age. It's just about as funny, and the animation is better. The plot is simple: Anthropomorphic animals of the Ice Age have to deal global warming: flee the valley or die. This "plot" is just another excuse for a dysfunctional family road movie, the Ice Age version of Little Miss Sunshine.
Dad is Manny the melancholy mammoth (mouthed by Ray Romano). There's a female mammoth (Queen Latifah) who thinks she's a 'possum. There are the hyperactive, trash-talking kids (Ellie's 'possum brothers). There's the sabertooth tiger who harbors a secret fear that he must overcome. There's Sid the comedy-relief sloth. And for padding that has nothing at all to do with the rest of the movie, there's the irrepressible Scrat.
The two best scenes are Sid's encounter with the horde of Sid-worshiping mini-sloths and the Busby Berkeley-inspired dance number with buzzards.
'Possum fans (Terrill Lee Lankford, take notice) should definitely check this one out.
