Doctor Who: Every Doctor's DEFINITIVE Episode

The success of The Caves of Androzani dictated the tone of the following season, giving rise to some grimmer, more violent Doctor Who stories. One of those was Vengeance on Varos, but unlike some other examples at least it was attempting to make a comment about violence on screen.

Varos is Colin Baker's finest hour as the Sixth Doctor, as he goes toe-to-tail with slimy capitalist Sil in his attempts to bring down the planet's corrupt regime. It's an episode that's not without its controversy – the acid bath, the fact that it revels in the very violence it's supposed to condemn – but it does give Colin Baker his best material.

The Sixth Doctor's moral outrage is always something to behold, and there's a lot to go round in a story that features corrupt officials, evil corporations, bizarre genetic experiments, hangings, and dehydrations.

You don't get that on Gogglebox, do you?
