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.
I didn’t watch Better Call Saul back when it was airing because I thought it was a soulless cash garb riding on the popularity of Breaking Bad. Years later I started watching it randomly and now I think I might like it even more than Breaking Bad
