I used to look forward to this show every week, and now I will let it slip by for weeks at a time before catching up. I just happened to be bored when I saw this episode online which is what made me watch it.
That's just my long way of saying I agree that this hunt for Red John has been over played. Their making him out to be this mythical person that I don't see how they will ever be able to deliver on it. Also they killed Loralie so seeing her again in this episode just reminds me how much her dying annoyed me.
With their list of 7 I can honestly only see it coming down to two people. The guy from Nikita and the lab tech guy. Lab tech guy would be way to spot on from the Moriarty from Sherlock which just leaves the go to actor for bad guys.
Stiles ran Visulize so he couldn't be Red John working at the barn since people would remember him. The FBI guy from the hunt for Loralie episode and the one who wanted Lisban to work with him aren't good enough actors that Red John would just seem cartoonish. The FBI guy who snuck into Patrick's room is to spot on to be him. I forget the 7th guy but that's why I'm going with the guy I picked.
