"Kryten" introduces us to the eponymous house robot (here played by David Ross), although after this first episode he was not to reappear until series 3, when Robert Llewellyn made the role his own. Then in "Better Than Life" the show produced one of its all-time classic episodes, as the boys from the Dwarf take part in a virtual reality game that's ruined by Rimmer's tortured psyche. Other highlights include "Queeg," in which Holly is replaced by a domineering computer personality; the baffling time-travel paradox of "Stasis Leak"; the puzzling conundrum of "Thanks for the Memory"; and the astonishingly feminine "Parallel Universe." --Mark Walker
