ahhh... bugger.

Well, it's over now, nothing more to be said, but really? Not only is Red John literally the opposite of anything I, or apparently Patrick Jane, had expected, but Jane also killis him?

This'll sound a bit cliched, but here's MY perfect ending:

Jane is genuinely hopeless, he's lost, there's nothing more he can do, other than to hope that one day he will know the identity of Red John. He's in the wreckage of his old house, sitting in the room where it all began, thinking about the past, the present and the future... then suddenly, that eerie voice, the one he hadn't dreamt of ever hearing again comes from behind: "Hello Patrick." He whirls around to see a man, his age, handsome but arrogant looking (the son of Brett Stiles did someone mention?), smiling amusedly at him, "It's been a long time coming my friend." Jane stands staring at him for a moment, transfixed; he knows who this is. Then a length dialogue, something quite akin to Strawberries and Cream's Red John scene. This man is likeable, yet detectably callous, insensitive, often referencing the loss Jane experienced at his hands.

The one thing which I'd keep from Heller's ending is the line, "It's over, I've won."

Then Red John gives Jane the final ultimatum; make peace, or die. Jane (obviously) chooses death. 

With a sigh of sadness, not frustration, RJ pulls out a gun, "Have it your way..." But Jane is ready for him grabbing his own gun from his pocket, shooting RJ in the leg.

Laughing hysterically, RJ says, "It was always going to be you or me, wasn't it?"

"Yes."

Jane stares into his eyes, holding his gaze for a long moment, before slowly lowering his gun.

"What, after all this pain, suffering, you're too weak to kill a man?"

The answer is slow, measured, "No... I have no weakness like that... But the game is over, it's over because I say it is..."

He turns, and walks down the hall, the camera staying focussed on the kneeling RJ, capturing the look of shock and anger on his face. He turns his gun on the retreating figure of Jane, but can't seem to find the will to pull the trigger. Slowly, furiously, he turns the gun upon himself, staring into the barrel. 

A gunshot is heard as Jane leaves the front door, and a small smile can be seen on his worn face.

Ahhh Bruno, Jane didn't care about whether he was cleverer than Red John or not, he only wanted to see his face and beat him, truly beat him, something which merely killing him would never accomplish... oh well, back to Sherlock...
