Luckily, I was wrong.
Aesthetically, I feel mixed about this movie. The art direction was brilliant: claymation-style characters, every one of them unique. Of course, it's still got that vibe you get off Family Guy and the Simpsons, but that seems pretty much inevitable in American animation. I hate that vibe. It makes my skin crawl. It's like the sound of teeth scraping along a fork: I want to punch the responsible party. But I think in this movie it was well-done, at least. Norman's hair, his sister's hips, Josh's shoulders -- exaggeration was used to great effect.
Music was forgettable, but served its job. Voice acting was spot-on and fully immersive. There was nothing to criticize, but I don't really know voice actors that well, so I don't have all that much to say.
The story, too, wasn't anything particularly groundbreaking. Kid talks to the dead, everyone thinks he's a freak and doesn't understand him, kid winds up on quest to prevent local witch's lingering curse from destroying entire town. You can guess the rest from there -- it's fairly straightforward. I guess if you're bad at predicting plots, you'll be surprised, since a couple of the people I watched the film with were somehow shocked (I have no clue how) by the "surprise" twists.
So if the plot isn't the hook, the art not my cup of tea, and the sound whatever, why did I like Paranorman?
This film was put together brilliantly. It was dark for a kids film, a little raunchy, and very aware of exactly which stereotypes it was fulfilling. I don't think it was a great thing to take the children out to see, but it's perfect for the high school/college environment. There were so many little things the filmmakers did, from the grand speech of the lady with the mud mask to the clever little pieces of the mise-en-scene. They chose to be daring in their presentation of the final confrontation, and still gave the viewers their happily-ever-after.
If you haven't seen Paranorman yet and enjoy it when the adults are wrong (because this is one of THOSE films, another reason parents likely won't buy this DVD), I'd say ferret out a copy and give it a watch.
