My favourite scene in this serial has to be where Chase is going to kill the Doctor and Sarah Jane, but first for some inexplicable reason takes them to his 'green cathedral' and plays the worst synth music I've ever heard in my life. It's so bizarre and is honestly 85% of the reason that Chase works as a villain for me. Most of the special effects are pretty impressive for 1976. Whilst the wandering Krynoid in its early stages is very clearly just some guy in a silly suit, the initial pod special effects look brilliant, as do the initial stages of transformation. I especially like the fact that even Keeler’s bald spot goes green.
