Breaking Bad (2008)

Breaking Bad (2008) achieved what few dramas can: transform from a cult favorite into the most-watched cable drama in history, culminating in a Guinness World Record for highest-rated series (Metacritic 99/100). Vince Gilligan's 62-episode arc of chemistry teacher Walter White's descent into meth kingpin "Heisenberg" defined antihero storytelling for a generation, proving slow-burn character arcs could sustain massive audiences. Its finale drew 10.3 million viewers, capping a rare case of a show whose audience kept growing season over season as its critical reputation grew. Cranston's performance set a new bar for dramatic transformation on television.
