Shows, in my opinion, are just getting worse and worse. The channels I used to watch, and still do from time to time, are now shadows of their former selves. Cartoon Network has been in the crapper since 2007, and haven't produced anything worthwhile to me since. The only thing I watch for some reason is the Regular Show, which is definitely should not be geared towards younger kids, which I would assume CN tries to target, but I guess things change. I really don't see a reason to mention reality television shows, as most of them are just downright awful, with a few exceptions.
I see a couple of us mentioning The Walking Dead, and I must say, it is definitely overhyped. Not enough zombie action to me. I also don't really like the MMA shows on TV now, ironically, as a martial artist; I guess I just don't like such brute force. Hence, here's my list.
