3. The Ark In Space
Also known as 'The One In Which The Monsters Are Made Of Bubblewrap'. Seriously. This classic serial from 1975 featured the Fourth Doctor, Sarah Jane and newbie Ian Marter facing one of the deadliest adversaries in Doctor Who history (no, not the aforementioned bubblewrap - it was actually the Wirrn, a race of human-sized insects) and it was enough to secure Doctor Who's third highest rating to date as 13.60 million tuned in for part two on 1st February 1975.
