Last week I binge watched Fargo season 1 . Really loved it...I watched season 2 during its original run last year.
If I had to choose which season was better, I'd take season 2. I really dug the split screen usage, and the music placement was incredible.... Although I must say, the use of cross-fading was very "Kubrick like" in season 1...and it's Billy Bob Thornton's greatest performance to date IMHO
Maybe I just gravitate towards the 1979 time period more than the 2006 setting of the first season.
