A year ago, I was intrigued ...

Question: A year ago, I was intrigued by the premise of Reunion, only to be greatly disappointed when it was canceled before the identity of the killer was unveiled. With all of the serial dramas (in the vein of 24 and Lost) that are being introduced this fall, which ones would you predict will end up disappointing viewers like me because they aren't allowed to provide closure, thanks to trigger-happy network programming execs?
Answer: Here's the other burning question about this suddenly popular genre. Fans aren't likely to be satisfied unless these shows get at least a full season's run, and even then (taking Invasion as a for-instance), if the ending is ambiguous and the show isn’t renewed, there’s still a feeling of betrayal. Serialized thrillers and mysteries are especially vulnerable, because unlike typical soap-opera cliffhangers, there are often specific climactic answers (as in the revelation of the killer in Reunion) that go unaddressed if the show is yanked too soon. This was a hot topic at the summer's TCA press tour, and each of the network heads promised they would try to provide some sort of content for fans (perhaps online, in a blog or podcast or something) if these individual shows ended up not succeeding. As the season progresses, we’ll have to see how well they uphold their end of this often one-sided bargain. Or if we're lucky, some of these shows might actually click, and it won’t be such a problem. But to answer your question more directly, I imagine many of the new serials will have a hard time getting to the end of their first-season stories: most notably Vanished, Kidnapped, Six Degrees, Jericho (which opened better than I expected) and possibly Heroes (which may be hard to follow but, in the first three episodes anyway, has some of the season's niftiest cliffhangers). We'll know more once we see how these shows sustain over the next few weeks.
