No one could ever be useless if they watch the Walking dead haha. I watched the whole series 4 times now. Well, aside from the end, I've only seen that twice. I first started watching it in 2011, after my friend told me to do so. I had seen the odd (half) episode or so, late at night on a rerun, but never got into it. Probably because those episodes were somewhere halfway season 1 or 2.
Anyway, she told me to watch it and I listened, and I was hooked.
I faithfully waited for the next season, and the next, and the next. I was happy that they came with Fear the Walking dead, so I didn't have to wait another year, but it didn't live up to everything the Walking Dead had.

Then, I think I was just in Season 6, my eldest daughter became interested in it, and asked me to watch with her. So I started all over again. Didn't mind.
Just before we started on Season 9 (we were a little behind, she left our home and moved away, so there went my watch buddy.
So I had to sit through some very emotional episodes on my own, crying lonely tears for the losses. LOL.
Anyway, I watched the rest on my own, and then my son wanted to watch it last year, so I binge watched TWD, FTWD and most of the spin offs with him, in chronological order.

There has hardly ever been a series that had me so emotionally involved, especially not something with zombies! (although I never understood why they called them walkers, and not zombies. It's not like zombies hadn't been on TV before that haha.
Well, not true. I felt the same kinds of emotions when I watched Breaking Bad, but that's about it.

Anyway, loved your write up. Now I'm going to watch Daryl Dixon. :)
