I had such a troubled relationship with The Expanse S01 as well.
I read the novel and thought the writing was meh, so I dropped it at some point.
Then my friends were telling me the show was great, so I gave it a go but got bored at about the same point and stopped.
So other friends insisted it was great, so I tried it again with my GF. She complained about the show, but we decided to really see what this show was about and stick with it no matter what.
Turns out I thought the story was heading into some sort of “space zombies” tale, but I couldn’t have been more wrong. And the characters I thought were so bland and indistinguishable in S01 gained so much nuance that they’re now so clear in my mind years later.
It’s definitely one of my favorite sci-fi shows of all time. I guess it’s worth listening to your friends and sticking with things sometimes.
