It's a guilty pleasure at best. The special effects are great for it's time, and are still quite remarkable today. The crew of a space ship encounter a large exploration ship with a strange scientist who wants to travel into a black hole and discover what lies on the other side. This is one of Disney's best and most creative films ever, and it has a great cast, Anthony Perkins, Ernest Borgnine, Roddy McDowell as the robot Vincent and Slim Pickens as the robot Bob. This is one of my favorite science fiction films as well as one of my favorite Disney films, it's a bit dated by today's standards, but it's still epic. The ending really leaves you wondering where the black hole really lead.
