As Lost taught us, you should probably base whether you want to watch a show on whether you are enjoying yourself. Even if a show is going nowhere, it can be entertaining as encapsulated episodes. It's not like reading a mystery novel and being afraid that someone will rip the book out of your hands before you get to the last chapters, and even in that case, the same Q applies: are you enjoying yourself enough to stay invested? If not, the answer as to what to do is obvious.
That said, I will sometimes put a "watch" embargo on shows I have recorded if I think they might get cancelled, but that applies to shows with little other redeeming value than the overaching story, that I am on the fence about. It is not uncommon for me to hold a whole season of some luke-warm CW show, and end up dumping the entire series when it is obvious that I will never want to watch it. 2 TB HDDs allow that.
On the other hand, I got to ep 4 of Last Resort and decided to hold off watching; it looked like it was doomed, which it was. But I had eventually had all 13 eps and started watching it again, because it still was above the Mendoza line, even being cancelled. It often does not matter if the story eventually goes nowhere if it is still a good story otherwise.
The House of Cards experiment on Netflix is interesting in that they made all 13 eps available at once, and lots of folks ate that up. That says something for the release model, but it sure does not brighten the dim future of the conventional advertising model.
