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 first season of Spartacus. My dad recommended it and I tried watching the first few episodes. Spartacus gets his ass kicked a lot at the start of the show. You’d get a glimmer of hope, then he’d fuck up and nearly die again. My dad insisted it would get better and I watched one more episode and he has his first victory in the arena. I stuck with it from there and thoroughly enjoyed the rest of the first season and the prequel season.
RIP Andy Whitfield. I tried watching the third season which picks the story back up after the first, but I just couldn’t get into it. I don’t think it was necessarily Liam McIntyre’s fault, the show just lost it’s rhythm after the setting change.
