There's this thing about really good Doctor Who stories. The Caves of Androzani has a plastic dragon. Talons of Weng-Chiang has a cuddly gerbil. Otherwise wonderful tales let down by a badly-designed monster. From the fully extant (ie on film) Episode Two, the Yeti are very slightly cute, but they're also huge and, frankly, I'd be frightened of Teletubbies if they were being controlled by Wolfe Morris' chilling Padmesambhava. Sounds rather perfect so far... It's a story of Tibetan Warrior Monks besieged from outside by the Abominable Snowmen of the title, The Robotic Yeti, and from inside by The Great Intelligence, an alien force set to consume the monastary today and the world tomorrow. The Doctor's been here before (but we've never seen that officially and the script accomodates the Doctor's familiarty without any of the quite unnecessary fuss and confusion the programme would descend into in the mid-eighties, when this sort of thing happened more often). Troughton is as usual superb, the 67-68 season once again proven his finest few hours, and Victoria (only her third story) still surprisingly stands up as a weak but sympathetic young lass. Jamie gets to have an idea and the Doctor says the immortal line "Bung A Rock At It!" The narration read by Frazer Hines, is quickfire but fluid and intelligently written, and if you've seen Episode Two, plus the stories that surround it, it's no trouble visualising such wonderful scenes as the Cliffhanger to Part Three, where the Yeti behind Victoria... or where... hey, just listen to it.
