The portrayal of Toberman is quite an unfortunate racial stereotype, a product of the period. Yet nonetheless he's allowed to be somewhat heroic toward the end, which redeems it somewhat.
They didn't even bury the man. I liked how he spooked Jamie though.
I tend to think that the Baker Episode will be The Talons of Weng-Chiang
As much as we all loved Elisabeth Sladen (who played Sarah-Jane), Leela is perhaps what many remember about the fourth doctor. Talons is rather like The Prisoner episode Hammer into Anvil--you are looking for a stock episode to showcase as much of the characters as you can encapsulate into one show.
As for Pertwee, I'd like The Dæmons.
