Just watched the Red John episode and, although parts of the episode were good, overall I am disappointed.  My guess was McAllister or Haffner but the way this ended, it just seemed off.  Why was Red John still breathing when he was supposed to be dead?  Why was Red John calling 911?  Some of the acting by the support actors such as RJ's pal, the lady in the church the screaming family, etc. was just lacking.
