My family (wife, young boy and girl) saw this on BBC TV one Christmas, (maybe 1990? - they'd have been 6 and 5 then) and videoed it. It has since become a staunch family favourite. Graphically superb and totally psychedelic, it is also one of the most spiritually moving and profound things I have ever seen. Good versus evil, in the form of a child with spirit guides, versus nasty dragons. Some of the lines are fantastic, too: "Now we can grow even more wicked - let's create some new diseases" - (just like they do at Porton Down in Wiltshire.
But that raises an interesting point - I've only ever seen it on sale with a Mandarin sound track, and English sub-titles - but the broadcast version was in English with no sub-titles. Anyone know anything about that? An absolute must-see for anyone with any sort of taste at all.
