From NetFlix:
In this fantasy adventure, the Dark Crystal — which served as the font of balance and truth — cracked 1,000 years ago, beginning an age of chaos. To restore order to the planet, Jen, the last of the Gelfling race, begins a quest to find a missing shard and heal the crystal. If he doesn’t complete his mission before the conjunction of three suns arrives, the evil Skeksis will rule forever. Muppets creators Jim Henson and Frank Oz co-directed.
Jim Henson, of muppet fame and now deceased, created this
puppetry masterpiece. The detailed scenes (especially the swamp)
were marvels to look at. It was NOT a popular success. It is not
animation. You have to be in the mood for a slow moving masterpiece.
In fact, watching the turtle-like wisemen lumbering along sets the tone.
I wonder if some of the scenes might not actually scare really small
children.
