Criminal Minds started out really well. A little bit of psychological and sociological background being introduced to the general public to get a grasp on criminal profiling. The episodes were entertaining, the characters relatable yet realistically flawed. However from season 6 on, this series just spiraled downward. The cases lost the grip they had had on the audience, became dull and left you cold. In an attempt to make up for unimaginative cases and the routine that had set it when watching the team profile, gore and violence was increased and to even it out cheesy background plots for the characters were added. Sometimes it's just better to quit while you're ahead.
