For me:
-The Expanse - The beginning was confusing AF and the politics didn’t make sense and seemed boring, so I quit. But then eventually after like a year or two, went to reddit and it was recommended again, so I just read some light spoilers and that helped me got through the first season. And then it has been an intriguing and thrilling journey.
The Good Place for me too but not the same reason. I just didn’t find it that entertaining, so quit after 3 episodes. But I saw it recommended so much alongside shows I do love and went back to it for a second chance and ending up loving it.
