I totally enjoyed this 60's slice of deep sea b-movie monster pie. The story was pretty good and engaging, and very weird the way the monster comes to be and both the miniatures and the monster are great! One of the best underwater humanoid sea creatures since Creature from the Black Lagoon. I don't know the history of the creature or who made it, but a lot of time and effort went into constructing that beauty! As a kid I remember it scared the hell out of me because of its size and speed. Not only that, there are a few suspenseful scenes in Destination Innerspace that work really well and I think still hold up today. Sure, the monster is not so scary now, but I'm still very impressed by the look of it which really made this obscure little gem worth finding again.
