Oh, I'm so sorry. I watched the first 4 seasons and finally gave up after the show continued to suck and go nowhere. I know A LOT of people like it, but I just hate, hate, hate this show. I keep expecting it to go somewhere, but it doesn't. There's no real suspense other than who will kill who next, that's it. No back story on the zombie outbreak or why it happened, nothing.
Now if you want to watch a similar type of show, watch, "The Strain". I feel like it's a similar premise, but it gets into a lot of detail, an overarching mythology, etc.
Like I said, I gave TWD a chance by watching 4 seasons, but I couldn't take it anymore after that.
Some of favorite shows are as follows (in no particular order):
1) Fargo
2) Mr Robot
3) Game of Thrones (obvious)
4) Broadchurch
5) Sons of Anarchy
6) Twin Peaks (an oldie, but such a goody)
