Personally, I adored Coraline. But, then again... that's just my type of movie. The art style initially turned me off, honestly, but the final product was just FANTASTIC. It was very... basic, in an almost low-budget way, but far more fluid than most stop-motion. The tone that Gaiman set works PERFECTLY with Henry Sellick's direction. I'll admit it's a very slow-paced movie, but, well, I think it was for the best. It moves along at a very slow creepy... a horror movie without any real "horror" for most of the film. It reminds me of classic horror films, with slow, deliberate camera motions for a lot of scenes. Really lets the mood sink in, y'know?
And by the end I had a wide grin on my face. So, yeah, I wouldn't say it's out of line to call it the best of the year... Ponyo was great, too, but Coraline was wow-inducingly great.
...and, just to note, I didn't even see it in 3D. If it's really that better, well, I should probably get on that.
