It is not always a bad idea to give a show a chance, especially if it new or different than what came before it
I watch very little tv, but through Netflix and Amazon Prime I have checked out shows like the Blacklist, falling skies, and arrow, and I enjoy all three. Arrow led me to The Flash, which I enjoy also.
The seams in blacklist were obvious in season one, but season two exposed it as a very pedestrian show, save for Spader.
