I'm not alone in being confused as to whether this was a very bad film and due a score of 1 or a very well made bad film and deserving of a 10, so I decided to give it a 7 as I enjoyed all of its silliness. An interesting plot with cheaply done special effects and it's amazing that this silly film was being made at the same time as Star Trek, this is a 50s style Sci-Fi film which was made in the late 60s. Worth a watch.
