That's admirable, especially if there is one you weren't particularly fond of the first time
I do have to grit my teeth with some of the shows I have to watch, but most network series are professionally done, even if it's not quite down my alley. It's the cable stuff like A SHOT OF LOVE or COLLEGE HILL INTERNS that make me cringe.
Now, I'll be the first to admit that it's MUCH easier to review these when you've already seen the shows before. When I finish NCIS, I'll start on THE SHIELD, and I devoured all 10 episodes in that set when they were aired originally, so it's much easier to follow something when you're hitting it for the second or third time.
