I wouldn't want to spoil by revealing anything you haven't watched. Sounds like you are pretty much caught up since you know about Alexandria.

Carol is also my overall favorite character. An example of how the TV series differs from the comic, Carol committed suicide by zombie while they were at the prison. She is a totally different character in the series. They don't mind killing off major characters but I would hate to see her go. Thankfully there is no sign that she is in any danger.

I only started watching TV with any regularity when I discovered TIVO 6-7 years ago. I also could not commit to being in a certain place at a certain time. Even with TIVO there were few shows I cared to watch, what with reading and my outside activities and carousing.

I am so old and worn out anymore TV and a little computer stuff is about all the entertainment/activity I can handle. My eyes are not that good and even back lighted E books are somewhat painful to digest. So, I watch a lot of TV these days and it keeps me entertained. No TIVO anymore but Uverse provides a good DVR that can record up to 3 HD programs at a time, so I am all set. :)

Netflix is a great source for serialized TV. I caught up with Breaking Bad on Netflix when I discover that gem. Mad Men is another series that I may or may not get around to in the future. My limited exposure to Mad Men makes me think that I lived it, and for some reason this makes me reluctant to get involved with it, but maybe someday.
