Television has entered a new age - never before has the medium produced such a high volume of content. Not only has the output increased but so has the quality; the days when characters were killed off in one season and walked out of the shower in the next, retconned by a convenient dream, are mercifully over.
That episode of Dallas is now infamous for ripping off the audience with a deus ex machina worse than nuking Indy in the fridge but what about the televisual triumphs that ended up creating more narrative problems than they solved? Daring story arcs can leave shows directionless, the bravest of character culls cannot be reversed and occasionally there are the episodes that are just so creatively perfect that all else pale by comparison.
Twin Peaks revealed the killer too soon, Sherlock killed off Moriarty and never really recovered, and Game Of Thrones put all its eggs into one frosty basket, splitting the final season in half at a time when all the threads should've been pulled taught. These decisions produced some of the best television ever made but ultimately creatively doomed the remaining episodes - were they just too clever for their own good?
