Another from the set of "20 worst SF films available cheap on dvd". Unlike Eyes Behind the Stars, this one was at least watchable, filmed in something approaching normal English and had a coherent plot.

On the other hand, it was extremely silly. The influence of the early Avengers was obvious, the ending was completely stupid (oh, then let's be friends and we'll stop attacking you), and there were some amusing moments...but not enough.

Skip it unless you are just one of those people who HAS to watch really really bad sf. And if you are, you might want to consider professional treatment...
