I disagree. First of all what about critically acclaimed but horrible ratings? (Arrested Development / Community / Friday Night Lights / Terriers). Should I not give those a chance because the ratings were bad? Consider the case of Studio 60 which had abysmal ratings (after the first episode) and was cancelled fairly quickly. Should I not bother? Or how about a show with terrific ratings but not critically acclaimed? A lot of folks are watching and enjoying it, so perhaps I should stick with it? That's what I mean, there's no hard and fast rule. I think really, go with your own tastes. If you know the kind of show you will like, watch those. Who cares what critics think? They are TV viewers just like you and me. And since there's SO much out there, if a show doesn't grab me pretty quickly, I really don't have the time and patience to keep at it. I stuck with Breaking Bad WAY too long, even though fairly early on I knew I wouldn't like it. I gave it 1 1/2 seasons. Time I wish I had back to watch something else. I'm sorry, giving a show THAT much time to grab you is ridiculous.
