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.
Parks and Rec. It copied The Office too much in season 1. Came back after a few years and couldn’t believe how different season 1 and 2 were.
Took me 3 tries to get past the first season. I recommend people just start with season 2 and then go back and watch season 1 if they want to know why I recommended they start with season 2.
