Unfortunately, The Krotons largely deserves its somewhat infamous reputation. I think the story is okay, it gives some interesting stuff to the Second Doctor and Zoe, both really shining in these episodes but otherwise so much works against this story. From the effects looking pretty terrible while at the same time relying pretty heavily on them, to a story that too often meanders, this is a strong example of the kind of Classic Doctor Who story that might be worth watching once, and then never again. It very much reminds me of Galaxy 4 but with the Second Doctor on a few levels, including quality of effects and a story with some moments but a lot of unfocused writing and lost potential, too.

I think "dull" might be a key word here that I've seen in another review. That about sums up my emotional experience of The Krotons overall. It is a bit of a snooze-fest and feels like it could or should have been a lot more fun than it wound up being.
