I wasn't expecting much from this movie. I mean, I like Rocky and Bullwinkle, but it seemed like stretching out the short cartoon to fill a whole film was a potentionally bad idea. But it turns out they managed to make something worthwhile.
It's not a laugh riot. But then again, neither was the original cartoon. What it has going for it is a lot of corny humor, a ridiculous plot, and, of course, Robert Deniro's dead on impersonation of Fearless Leader. Really, it's kind of scary how well he does it. And the entire movie could've been terrible and it still would've been worth it to watch DeNiro spoof his "Taxi Driver" role.
The movie's humor comes from its dialogue, its strange characters, its patently absurd plot twists, and of course, the trademark breaking of the fourth wall. There's even some intelligence behind this silliness, though most won't get past the puns to notice it.
Look, I liked it. I can't say much more than that. It's amusing and the animation is really quite amazing considering how bland the original was. And it's got a lot of cameos, too. Worth seeing.
