Hot on the heels of cancelling Debris, NBC is advertising what looks like another upcoming science fiction McGuffin mystery type show. Over and over, network TV puts on shows like this that I think are interesting - Surface, Earth 2, FlashForward, The Crossing, The Event, Emergence, Touch, Second Chance, Reverie, etc. - only to cancel them after one season, with no resolution to whatever the mystery was. It drives me bananas when I start watching yet another of these shows on NBC, CBS, ABC, or Fox, and then they cancel it.
My prediction is that La Brea, a show about a giant sinkhole in the middle of LA which is really a hole to a primeval world, will join their ranks. Potentially intriguing premise, and we will learn nothing before it is cancelled.
Do they start these shows with the assumption that they will likely not last long, but they will get enough viewers for one season to make some short-term bucks off them? If the ratings turn out to be good enough, they keep the show around and only then do they worry about making the plot possibly make sense?
