Fawlty Towers delivers classic British comedy by way of Cleese's delightfully neurotic character, whose attempts to advance his business always backfire in hilarious ways. His brilliance in the role is matched by the acerbic Sybil, who always manages to keep Basil under her thumb and dismantle even his best-laid plans. Their contentious relationship yields funny TV, even as it contradicts the very tenets of marital bliss.
... none of them can come close to explaining the actual magic of Fawlty Towers, because it's difficult to describe the point where personal chemistry, creative genius, and pinpoint comedic timing come together. Like any unique work, it has to be experienced to be appreciated.
