There are multiple cuts, and the one I grew up with (I think a VHS recording from cable) instead has a longer introduction [0], with detailed exposition while panning over paintings of its world. Watching it at around 11yo, I found it comprehensible (if bizarre), and compelling, before reading the book years later.
I'll have to look again to see if this cut is finally available in any official capacity; I've only ever managed to find a stitched-together fan edit. It's flawed by any measure (many sets and effects that looked good on VHS don't hold up on HD), but I actually enjoy most of its creative license, and the longer cut mostly holds together IMO, in a way the theatrical doesn't.
