I have to say it's not entirely the choice of Red John I am disappointed in but the lack of emotion from PJ. This is the first time he comes face to face with this evil man who murdered his wife and child. I was hoping for some real intense emotion from Jane.. Some sort of outlet of the anger he has carried around for ten years but Instead he just sat there calmly?!
So yeah in my opinion the confrontation was disappointing and too many unanswered questions :( I really hope tonight's episode has some differences :(
