This show was absolutely brilliant. Did go down hill at the end but first 4 seasons were amazing. I do feel that they had a missed opportunity with Lou Kelly's character. The fear she brought was amazing and the " I don't care attitude " Kate Box was amazing. I do think a spin off series on lou Kelly's first prison sentence is definitely needed and on why boomer didn't trust her. One character I didn't get the point in was Judy Bryant, that was just a pointless story and it's a shame they made Ruby's character weak. You always knew when a top dog was going to die as they were tired and fed up. They killed reds character off to early as well. A lot could have been done with her!!!
