A typical low budget sci-fi flick of its era, originally envisioned in 3D. It begins with a good set-piece in which a couple of scientists are killed in their laboratory - maybe deservedly, given the cruel experiments on animals they're conducting - before moving into a talkier investigation. Eventually, our wooden heroes realise that a couple of robots have gone awry, leading to a fun, perilous climax. An early entry in the 'killer robot' sub-genre of movies, it's very dated, but perhaps that's part of the fun.
