Instead, the ability to provide a jokey running commentary about any given old sci-fi movie doesn’t necessarily reveal that the movie sucks, but instead, is rich enough to provide multiple readings. When it comes to This Island Earth, the answer is a very qualified yes. Yes, the aliens in This Island Earth are largely hostile, but it takes a while for us to fully realize that. For this reason, This Island Earth shouldn’t be condemned as one of the worst sci-fi movies ever. This Island Earth is available for rental on Amazon, Apple TV, and elsewhere.
