Doctor Who: The Tom Baker Years Season 15 Serial 6

It was a good Gallifrey story, seeing the Doctor acting mad with power was fun, but unfortunately, it got ruined by the ending. I loathe "companion leaves out of love" exits, they're boring and unoriginal, it was extremely out of place for a character like Leela, especially with another character she barely interacted with. It could have been a 4/5 story. but the ending removes half-a-star.
