I don't understand why people are giving this episode such a hard time. I thought it was a brilliant ending to the saga. There was always something sinister about McAllister and masquerading as a hillbilly cop was genius. Yes, there are questions unanswered, but yes there are still episodes to come and we will find the answers we are looking for. This episode was about revenge- one man's battle to conquer his demons by going through with murder. There were poignant scenes of mothers with their daughters and we saw Red John's 'delusions of grandeur' exposed. Patrick didn't just kill him- he reduced him to a sad, desperate figure crying out for mercy- appealing to Patrick's morality and to the police authority that he had worked so hard to corrupt. I think Brice Heller and the team really made this work and the look in Patrick's face as he literally squeezed the life out of Red John was startlingly moving.
