Given that I've watched Interstella 5555 more than once, it seems fair to conclude that I like that movie:
Like Pink Floyd's The Wall, the music for Discovery and the storyline for Interstella 5555 were conceived simultaneously. The videos for "One More Time" and "Harder, Better, Faster, Stronger", which had both seen a fair bit of MTV rotation around the time of the album's release, were not simply clever vignettes for the songs, nor was Discovery purely a film score -- in fact, Interstella 5555 makes clear the degree to which each influenced the shape of the other. Ultimately, Daft Punk intended Discovery to be heard in the context of Interstella 5555, and it's no wonder: Matsumoto's animation enlivens some of the less formidable tracks, and the details of scenes in Interstella 5555 often are inspired by the music itself.
Beautiful 70's style animation seamlessly integrated with great electronic tunes, with fine direction. What's not to like about good storytelling?
