Doctor Who episode 667: Paradise Towers – Part Four (26/10/1987)
‘Bring them all out, all the nasty human beings. The Caretakers, the Residents, the Kangs, all of them.’ I think it’s mostly Briers as Kroagnon that really irks fans. The Chief Caretaker was a heightened version of his Ever Decreasing Circles character, in keeping with the other inhabitants of the Towers. But Kroagnon is just a joke performance that’s only occasionally funny (the look he gives Pex when they’re hurrying through the corridors). A more interesting choice might have been to tone it right down, so that Kroagnon and the Doctor suddenly become the only characters in this world with any gravitas, worthy opponents. Instead, it equals Graham Crowden’s death scene in The Horns of Nimon without the excuse that Briers didn’t know it was a take rather than a run-through. Fittingly, for such a rubbish villain, he gets a rubbish death scene – pushed through a door and exploding, rather than anything more creative.
