Did you ever watch The Sopranos? Same creators as Sons of Anarchy and it's on Amazon Prime.
I watched five seasons of Breaking Bad in three weeks or something crazy. Once I started I couldn't stop. I barely slept and took time off work so I could finish it. LOL It's on Netflix.
I keep meaning to check out Colony on Netflix. It has Josh Holloway from Lost.
It might be worth signing up for a free month of HBO Now stand-alone streaming service to watch Game of Thrones. You could always cancel once you're caught up, or move right on to Westworld.
