I have not owned a "real" (i.e. broadcast or cable) television since early 2005. From 2005 until 2012, I watched nothing except for DVDs on my computer from time to time. Then I got streaming Netflix in 2012, and I've had it ever since. Added Amazon Prime a few years ago too. Still don't watch broadcast or cable T.V. – only "on demand" piped from a computer through an external screen – which got added to the household when my future wife moved in to my place in 2014. I didn't even have a screen outside of my laptop till then.
I/we like murder shows, primarily. Cold Justice, Homicide Hunter, The Forensic Files, etc.
I've binged through several T.V. series since getting streaming services. Better Call Saul, The Handmainden's Tale, The Man in the High Castle, Breaking Bad, Medium, Vikings, Fargo, Twin Peaks, the new Battlestar Galactica, and many others. I fully realize that some of these are horrible shows, but sometimes I just get hooked anyhow (sometimes thanks to my wife's desire to see them).
I have not seen an episode of Game of Thrones yet.
The hands-down worst show that I have actually seen all of (well, at least seasons 1–7) is The Walking Dead. It is an utter pile of flaming garbage, and has been from the start. But I'll usually quickly blow through a season about a year or two after it has aired. Don't ask me why.
I'm trying to get my wife to start Goliath with me, but no luck as of yet.
We've started a few that we soon gave up on. E.g. Dexter (a handful of episodes) and Ozark (one episode).
We watched 5 seasons of Mad Men, and then dropped it. Never a very good show, IMO, but at least it looked good. Once the fashion, design, cars, etc. started getting into the ugly late '60's stuff, we couldn't hang any more.
We watched literally every single episode of Frasier on Netflix, over the space of a few years. I had never seen it when it was on the air. I liked it a lot up until Daphne and Miles got together. Then it lost the plot, so we slowly wrapped up the last couple of seasons, more out of a sense of commitment than out of actual enjoyment.
