I thought a few episodes of season two drug a little, but Rick putting those two guys down was awesome! The show focused on Ricks compassion and morals for a lot of episodes, but it is really the first time in a while that they reminded the viewers that Rick was indeed a lawman and a good one at that. Last night was first time I have seen that Rick since the first ten minutes of episode one. He knew what those two men were and knew how to handle it with no hesitation.
Anyone thinking that those two guys were randomly killed are just flat out wrong. He knew that they were trying to feel them out to get to the farm and clean them out and there are more on the way.
We are missing the one thing that a post Apocalypse world should have plenty of; Morally checked out humans that will take what they want to survive. Shane could qualify down the road, but he is not quite there while he has Carl and Lori to hang his humanity on. There are more of that group on the way and the pace of the last seven episodes should be fantastic.
