Most of us following the show thought the reveal of Red John would be like Murder on the Orient Express.  In that story a trainload of apparently unrelated people contributed to the killing of the bad guy (who needed killing).  A very complicated scenario was woven into a tight believable clever story.  This isn't what Mentalist fans got.  Instead of Agatha Christy, we got something more like Larry McMurtry.  It caused much frustration, got us off balance, and left us wanting something more.I disagree with everyone that thought Sheriff McAllister was an unlikely Red John suspect who was chosen at the last minute.  If you recall, in Season 1 Episode 2 when he first appeared, the CBI set a trap to expose a killer by using Van Pelt as bait.  The sheriff showed up, but talked his way out of it.  Patrick eventually trapped the couple as the real killers and the sheriff was dropped from consideration.  I remember thinking that if the sheriff really was Red John, the way Patrick embarrassed him with the rock, paper, scissors could bring serious retaliation later.  However, just like CBI, I got distracted and forgot about him as a suspect.  Looking back with 20/20 hindsight, what better job could he have to hide his activities?Just think - CBI was within a whisker of catching him, but he slipped away.  Along similar lines, this is one reason that I think the lady in the chapel will become a major player in the story.Hopefully Bruno Heller hasn't used up his bag of tricks, so I'm going to keep watching.
