10 Insane TV Twists That Ruined Their Shows
6. Dexter
With an unreasonably brilliant premise (a serial killer who only kills serial killers!), Showtime's blackly comic series Dexter was always bound to be a blockbuster success when it hit TV screens.
However the bloody, disturbing show adapted from the best selling novel series could well have fallen apart if it weren't for the efforts of Kill Your Darlings star Michael C Hall as the eponymous anti-hero and genre heroine Jenifer Carpenter as his tough police officer sister.
The bond between the two was poignant and tragic as Dexter remained close to his sister despite having to hide his sick hidden life from her.
That is, until the show's seventh season saw her stumble across a bloody clean up job, prompting everything to come out into the open and...
A widely reviled incest subplot, followed by an ending wherein Dexter fakes his death and becomes a lumberjack?
Sure, sounds perfect and not at all devastating for long-time fans.
