The first time I watched the pilot, after hearing about the show over and over again, I was like, "Meh, this show is too dramatic for a zombie show", and didn't even finish it. Several month later, I tried again and once I got to the 3rd episode, I became hooked.
I had a similar experience, I stumbled across TWD while channel surfing and when I tuned in, it was in the middle of a bunch of zombie killings and I watched for a few minutes and thought, what a bunch boring bull **** and turned it off wondering why everyone was so enamored with 60 minutes of zombie killing.
A few years later, S5 was already over and I stumbled across a marathon rerun and happened upon it right as the pilot was airing. After about 20 minutes, I was thinking holy ****, how did I miss out on this and spent the next 2 weeks binge watching every season.
Personally, I think this is a show greatly enhanced by the binge watching option. Having to be cliff hung to death from commercial to commercial and episode to episode would have caused me to lose my interest and bail. Being able to get my fix through the binge kept me hooked and wanting more.
I dont watch week to week as each new season occurs, I let the entire season build up in my DVR and then binge out. I have a feeling I wont wait to watch the first episode of this coming season because spoilers will be virtually unavoidable after its aired
