(Not the OP) I can’t say it was ground breaking, as I was a kid at the time, but it was one of the great movies of my childhood. I remember watching it many times over. I do remember the characters seeming less real, and I still knew they were puppets. But this was also the era of Sesame Street, so a movie by Jim Henson that had puppets was kinda normal. I think the fact that my parents talked about it so highly probably answers your question more — it was something adults appreciated. Ultimately, to me, the Dark Crystal wasn’t a great movie because I feel the story was there to service the technique, even if the technique was masterfully used. Maybe I was too young to fully appreciate it. Tron was much the same. At the time, you knew it wasn’t great, but it was still new. Like the targeting computer CGI for the Star Wars trench run, the effects weren’t great. Even at the time, it was a little spartan. But the effects moved the story, and worked well enough to not be a distraction (and you had never seen anything like it before). Tron was just as much about what it foretold as much as the CGI that was available at the time. But in contrast to the Dark Crystal, I liked the story behind Tron more. I would say that both were groundbreaking for how they pushed techniques of movie making forward. The world creation in both were amazing and they both set a new bar for future movies to meet.
