"Red Moon" is a superb, rather dark but complex episode.
Although the episode is self-contained, it provides lot of material for further development.
On the funny side, there're two psychics, one real and another fake. Patrick has part of his job done by Ellis Mars, in a rather funny way.
On the dark side, there're two men looking for revenge.
Todd Johnson had his revenge, Patrick is still looking for his own.
First pictures show a deer. When Jane meets Ellis Mars, he dreams about a tiger catching a deer.
Photography is great, with landscapes and elaborate camera moves.
As in other episodes, this episode adds some clues added to the Red John puzzle. I hope coming episodes will keep the momentum high!
