Thought this was an interesting to my earlier blog entry regarding the inevitable revelation of plot secrets and what it does to the sense of "mystery and wonder" -- it's from a NY Times review of a new TV show:
"... “The Prisoner,” shown on CBS from 1968 to 1969, is one of the most legendary television thrillers, partly because it wrapped after one 17-episode season. Most recently “Lost” on ABC kept core fans going for an improbable six seasons, but it also shed most of its intrigue long before it ended. ...The “Twin Peaks” axiom applies here as well: a show can ride only so far by suggesting, however cleverly, that things are not as they seem. Soon the creators must start revealing what really is going on."
