I spent a delightful afternoon with THE NIGHTMARE BEFORE CHRISTMAS. First, the stop motion animation as seen in Blu-ray is astonishing. Since it's a three dimensional world they're animating, the clarity and depth of high definition make it as close to 3-D as it's possible to get away from actual 3-D.
The movie is one that has had to grow on me over the years. Like NASHVILLE (which I was also lukewarm about when I first saw it), NIGHTMARE now is totally delightful and so creative, but when I first saw it, it just seemed creepy and weird. Original, certainly, but the music was dissonant and it just didn't thrill me. I did buy the first (nonanamorphic) DVD and watched it fairly often over the years finally getting its jokes and enjoying the Kurt Weill-like music a lot more.
In high definition, it's now one of the best films available on Blu-ray, and there is a Dolby TrueHD 7.1 soundtrack that is mind-boggling in its creation. They're finally given the movie the release it's always deserved.
