Apparently if you grow up watching films like The Never Ending Story or The Goonies you have fond memories and you still enjoy them now. Well, I saw The Never Ending Story as a child and I thought it was shit then.
This I missed as a child and I'm glad. I think it would have given me terrible nightmares and more to the point it was shit. No story to speak of, slow, tedious, terrible script, etc.
You can't group a film like The Dark Crystal with The Princess Bride or Labyrinth, two 80s films I also missed as a child but saw as an adult and actually enjoyed. The latter two films are clever, well-written and funny. The Dark Crystal lacked everything. It was like a big advert for what was probably a very boring board game.
