I blitzed the first five in one sitting when I was hungover and I loved it. But I haven't really enjoyed the last two episodes a lot, maybe waiting a week between episodes doesn't suit it, because it doesn't give me the feeling of really wanting to know what happens next and it also gives me time to reflect on how daft it is in parts. Malvo was stupid in the last episode, I hate this superhuman breeds of "cool" villains we're getting on so many shows and films nowadays. Molly is a very good actress though.
it's not directly based on Fargo the film though, just set in the same area. The plot and characters and year its set are all different. it does have lots of easter eggs to the film though.
