i loved it too...the imagery, the story was good, sort of a prince and pauper for those on psychedlics.
very creative, i was excited about it when i first read about it being made in a scifi book being sold at blockbuster, it seems they were discussing how a creator of labrynth was involved. Loving labrynth, naturally i was excited, but all the different facets of mirrormask exceeded any article i read discussing it's creation.
