I liked the season a lot too, but I almost stopped watching after the girl killed her sister. That was just a whole new level of dark that I wasn't expecting. It made me wanna puke. I mean...wow...guh...awful.

That said, the season finale was fantastic and left me dying to see the premier of season 5. It was available online legally at amc.net and so luckily I was able to tie the lose end. Can't wait for season 5 to come out on Netflix in a year.
