I thought it was one of the better episodes of the season. The Morgan story arc has been completed (at least for now). They addressed the mistrust of Michonne and she's becoming one of the more interesting characters in the story. Certainly the most interesting female character.
Finally, they continue to address the evolution of Rick's character from a World's boyscout mentality, to his current state of mind and it was symbolized in how they dealt with the hitchhiker.
