One of British TV's greatest ever sitcoms, the central question of Fawlty Towers – why the world's least hospitable man would go into hospitality in the first place – remains tantalisingly unanswered across 12 kipper-serving, Siberian hamster-hunting, German-baiting episodes. A straight zero on TripAdvisor, the very layout of Fawlty Towers itself offers comedy gold as Basil (John Cleese), his wife Sybil (Prunella Scales), waitress Polly (Connie Booth) and poor, benighted Manuel (Andrew Sachs) manoeuvre themselves (and the odd corpse) around its dowdy interior without ruining anyone's stay. Basil, needless to say, fails. Often and hilariously. And we wouldn’t have it any other way.
