These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: The Tangerine Dream score. Especially the...oh, to hell with it, the whole thing. If righteousness and beauty had a transcription in music, for instance, it would be the unicorn theme. The original score by Jerry Goldsmith is pretty awesome too. Because, well, it's Jerry Goldsmith.
Big Lipped Alligator Moment: Well, there's plenty of weirdness on display throughout the film, but during Lili's dance with the animate black dress, an evil-looking cherub comes to life on the tabletop. Lili doesn't notice it, it doesn't intervene in any way, and once the sequence is done, it's never brought up again.
