Simon Baker, the hunky Australian, who plays Patrick Jane (a psychic con man who has turned into a crime fighter) generates most of the energy for The Mentalist. Baker’s character is quirky (but cute) and carries the burden of triggering the murder of his wife and daughter by a psychopathic killer called “Red John.” And, as usual, the Season Finale returns to the Red John plot device. Much of The Mentalist is silly. In fact, Diane and I prefer the humorous episodes to the serious, grim episodes. I’m sure the conclusion to this final episode of this fourth season will be a cliffhanger.
