That's really hard!! I voted for 3, but I loved all seasons so far. I only saw seasons 1 - 3 one time, and maybe I would think differently after a second viewing, I don't know. After I saw one, I thought it was great, then after 2, I thought that was better, and the same with 3. Now I see previews of four and I think that looks great as well! The whole series is so different from any other mob/mafia movie, it just stands out!
