I watched the first two seasons when they aired, but then I never got around to watching the rest. Those two seasons were pretty fucking great though. I've heard it described as Game of Thrones with less death and magic but more sex, and I feel like it's pretty accurate.
I should really get around to finishing the show. At this point I should just watch it from the start because it's been so long, but I have so many things on my to watch list, ugh.
