Season 14, Serial #3, 1976
Is this the first episode without a companion? At first I was excited but by the third (of four) episode my attention waned. I think this is the first time we visit Gallifrey the home of the Time Lords, and no surprise they’re all narrow-minded, stuffy white geriatrics. The Doctor is framed for murdering the president of the Time Lords (what?) by The Master, who looks like a ghoul from Fallout because he’s past his 12th regeneration or some such sillyness. There’s a deadly game of cat and mouse inside a psychic matrix where the danger of death may or may not be real. The climax is reduced to eyeroll-inducing fisticuffs.
Also there’s a panopticon, which is pretty cool.
