Season 1
Season 2
2 was better but god I NEED MORE DANY!
Season 2 got me interested in the show. In a way, I prefer the pacing of Season 1 but the way the plots and characters of Season 2 was just far more interesting to me. And of course, it's just fascinating to me how the show moves on without its central character. Watching Sansa, Arya, Theon, etc. really come into their own is what got me hooked.
