I've never watched a minute of this series from any season but there's enough hype around it that maybe I should check out season one.
Check out season 5, 6 or 7. Seasons 1-3 are pretty slow moving, and rightly so.
Watch it however you want to, but I binge watched seasons 5 and 6, then 7, then I went backwards to season 1, cuz I cared about the characters by then. I have tried watching it from the beginning but it was too slow for me (all character development.
It's graphic in every way, but the main characters are very complex, which is nice. I hafta to admit, my favorite characters aren't in any of the houses. The Hound, Sir Gregor, Brienne of Tarth.
I might wait and binge watch all of season 8 as well. Watching it in real time sucks ass.
