As one of my all time favorite sci-fi films, I would give it 10 stars if I could. Super Disney annimation was 30 years ahead of it's time comparable to Star Wars and Avatar breakthrough technology of it's time in 1956. Mind expanding story line of the extinct Krell race advanced technology from the book "The Tempest". Outstanding visual effects and first movie ever with great all synthesizer sound effects. Characters include highly advanced Robby the robot, Anne Francis, her father, the captain and crew and...the invisable monster from the IDD. Has a sci-fi fan cult following, join in, a must see movie for all ages.
What's great about it: A Sci-Fi delight movie
What's not so great: Compare technology advances to Star Wars and Avatar
