I like watching TV series, but I can't imagine having the time to watch more than one concurrently. It's astonishing how many shows people watch. I think I'm on the right track (for me personally) by only having an interest in one show at a time. Currently it's Peaky Blinders.
I'll eventually watch GOT. There are certain shows, like Mad Men, that have such a strong following, you'd be silly to not peak at them.
