I remember seeing the ads for this film and feeling interest when I was a teenager, but I never acted on that interest at the time. It wasn't until 2005 or thereabouts when I finally saw it... and found out what I'd been missing. The concept is Tim Burton (Pee-Wee's Big Adventure, Beetlejuice, 1989 Batman). The music is Danny Elfman (Pee-Wee's Big Adventure, Beetlejuice, 1989 Batman... and, oh yeah, Men In Black, 2002 Spider-Man, and pretty much any film soundtrack since 1990 with an element of fun or whimsy). The film itself is a stop-motion musical about the citizens of Halloween Town, responsible for the human holiday, who discover Christmas and are so excited that they decide to take it over. If you haven't seen it, you should check out the opening song, "This Is Halloween"; if you don't like it, you're probably not going to like the rest of the movie. (I'm also going to question your taste, because... seriously, it's Danny Elfman.) Score: 4 stars out of 4.
