I didn’t read the books before season 1, so Ned’s death was the single most shocking event in TV history to me. But that also made it my favorite TV show, because anything was on the table (plus the writing, character development, and White Walker mystery were top notch). Never once did I think “I’m done with this show”.
I read all the GOT books between seasons 1-3, so I knew the Red Wedding was coming. That episode was more of an anxiety watch for me than shock.
I haven’t played TLoU2, but was unfortunately spoiled via a gaming thread last year, so I knew this was coming too. Same deal here where it was more anxiety than surprise
