There are a number of trends in computer animated children's/family movies.
One is the "rip off" trend. Madagascar->The Wild, for example.
The other is the "squirrels are teh funny" trend. There are more examples of this strewn through the genre recently. Ice Age and Ice Age: The Meltdown feature Scrat, a sabretooth squirrel. Following on his heels is Twitchy from Hoodwinked. ("I don't drink coffee.") The squirrel from The Wild had a thing for an unlikely female character... and then Hammy the Squirrel from Over The Hedge takes a page from Twitchy (going as far as ripping off his caffeine schtick at the end of the film, although in a different way, ala "bullet speed", all of which also feeds into the rip off trend, mentioned briefly above).
Honestly, I think this is where Doogal (our NetFlix selection for this edition of Daddy Weekend) falls short. No squirrel. Also, they didn't bother to rip off anything good. Anything.
John Stewart, providing the voice of the evil cold-manipulating spring... um, what was I saying? Oh, right. He panned the movie on his own show before its debut. And he was the villainous lead.
Squirrels. Definitely.
