I saw this film at the first public screening, in London last May, and it was and remains *beautiful*. Some of the US trailers don't do it justice, so you may need to take our word for it, or watch the SciFi London trailer. The anticipation and watching the film's development, and then going to see it, was one of the highlights of last year for me. Fantastic characters, the writing and world-setting is several times better than I'd ever expected (this is another thing you don't really get a teaser of when looking at production stuff and trailers). And of course the music and the voice acting - you'd do well to watch this film with as good a sound system as you're able to plug it into, or at the very least some good headphones. If the songs and music aren't enough (they are) there are also such treats as the Full Tim Curry Immersion Experience (as I think was GB Hajim's description). Something like half of this film's quality is in the audio texture and in the listening, and when you're holding that up alongside the work of the animators on Big Island, that is saying something.
This review may sound almost a bit overly-positive and promoting, but of course I'm biased: This is my favorite film in years, and I'm looking forward to watching it again. (just as soon as I figure out the best method of expediting a DVD to the UK)
