Planet of Giants, unfortunately, is just not very good. I was really impressed by the effects in the first episode and the effort clearly put forth into making this "planet" feel like something special. It still feels like it has a bit of a unique aesthetic compared to the larger franchise, which is cool.

Unfortunately, the story very quickly flattens out into nothing. The whole shrinking thing and larger story with the villain really doesn't amount to much of anything, and it becomes a very easy story to forget and leave behind, while the pacing and structure within Planet of Giants is very, very inconsistent. I feel like the Space Museum is a better showcase of the show being a bit more experimental in its early days, and it works a bit better than this story.
