15 Years Later, No TV Show Has Beaten HBO's Biggest Twist Of All Time

HBO is the undisputed home of prestige drama, and many of the best shows on HBO have changed TV. One of these is a series that packed such a punch with its major twist that it has still not been beaten even 15 years later. When done well, plot twists are a strategy that can turn a good show into a masterpiece that you have to watch twice to pick up on hints and foreshadowing. On the other hand, HBO's biggest twist only came with one warning, leaving viewers to analyze earlier scenes to work out where everything went wrong.
