Dubious science, effects so bad that sometimes I laughed, a mediocre plot with a useless romantic subplot, bad costumes, alien blood made of strawberry jam contained in old vacuum hoses, oh do I really need to go on?
If you’re going to watch War Between The Planets (1966), pray do not make your spouse, or your dog, watch it with you, for that wonderful person, or dog, may have loved you before, but they will not love you after.
Worst of all, it appears to be part of a series!
