Lost (2004-2010)
The great gamble that paid off: a six-season puzzle on an epic scale, with scores of characters and intricate plotting that truly put the myth in ”mythology.” Lost altered our view of the size and shape and momentum a TV series could maintain. When it ended, it was common to say that there’ll never be another show like it. I prefer to think the lesson of Lost is that another unique experiment can come along and become a mass-audience favorite.
