I am not a big Tim Burton fan, but this movie is in my top 3 of all time. Perhaps the fact that Halloween is my favorite holiday influenced my opinion, but I doubt it. The more I hear and read about this movie, the more I love it.
Based on a parody of the famous "Night before Christmas" poem by Moore that Burton wrote and illustrated while employed at Disney, this idea was stagnant for many years prior to filming. In many ways this was a good thing, technology was able to catch up to Burton's ideas.
In NBC, we see our hero Jack Skellington, aka The Pumpkin King, depressed as another Halloween passes. In the background we hear the residents of Halloween Town celebrate another wonderful holiday. But Jack is sad. The only one who notices is the Rag Doll-style woman Sally.
Other characters, including many town-monsters, are introduced. We meet the wonderful mayor with two faces, the evil scientist and his assistant, three local children and our evil boogie-man.
After an accident, Jack develops a plan to kidnap "Sandy Claws" and give presents out for Christmas in place of Christmas Town. You will have to view this movie to discover the rest.
The claymation is not what I expected, it was of a high quality and the movements are not jerky like the old Christmas Specials. Danny Elfman's music has little resemblance to his work with Ongo Bongo and "What's this?" (which Jack sings when he discovers the colorful world of Christmas Town) is closer to a tune mixed from Cabaret and The Music Man. The voices match the mouth movements nearly perfectly. This was a project from the heart and all the little touches to make it 'just' right show this fact.
