Start a New TV Series that I Know Nothing About

I was house sitting a few weeks back and got interested in this tv series called Downton Abbey. I had heard the girls at work talk about it but never had an interest in it. I figured that I might as well go ahead and get into it. I started watching it and got caught up into it. However I only made it to the end of Season 3 where they killed off one of my favorite characters. I don't think that I will pick it up again.
