Just saw the episode and...hahahaha it was so funny.

Especially when bertram dies, he gets shooted and he says "Ah." and the he crashes on the ground. Hahahaha

McAllister magically turns into Bolt running for 2 Km with a bullet in the stomach.

Red John defeated by a pigeon, check McAllister's face when he saw the pigeon hahaha

No answer to how Red John got the list of seven or how he managed to do what he had done during all the seasons.
From half episode until the end it's basically
"do you wanna know how I got the list right?"
 "No I don't want lalalalala I'm going to kill you evil bastard with no hair lalalala"

The only thing that I liked was that Cordero died, that guy was irksome.

Seriously, if this episode is the final chapter of Red John, then I'm Britney Spears.
