The Mutants reminds me a lot of Colony in Space. Both are very dry, boring stories that should be more exciting as we have the Third Doctor finally able to leave Earth. This serial just doesn't work for me, between the lame-looking sets and costumes and the even goofier story, I just did not get much out of these episodes. Even the Doctor and Jo just don't get any of their usual fun character moments here. It's just a sweaty, messy chapter in Doctor Who history I'd rather not revisit any time soon.
