Red John is still out there :)
did everyone miss the guy next to the slide (back to the audience)
also the Woman who tried to kill Patrick with a Knife!!!!!
game is still afoot

fandom never lose hope in the show or the writting
untill the very end! In doing so you run the risk of ruining ratings and having them can the show show before its natural end

Give them a chance to tell you the rest of the story
please as a fan have patience ... good things come to those who wait!
