My overall rating of "The mentalist"'s Season 4: 4/10.
So the whole idea/plot of this episode is so contrived and outright insane, it's impossible to take seriously or even jokingly, it's just hard to stomach, but I liked a certain video-game quality it seemed to have. "The mentalist" sometimes makes it easy to ignore the constant large-distance travel the characters do, or that each episode tends to resolve huge investigation in two days' worth of time or so, while people just lounge around to be interrogated at will. In this episode, the "fast travel" is basically impossible to ignore, and the scene where Jane and Lisbon meet Gretchen in the wine cellar has a certain cutscene vibe to it: maybe it's the location reminding me of "Dishonored" or something, but Gretchen's scene-opening walk and the "Hey, it's you again" "dialogue" just have that something. Gretchen's a breakout character for me with the few lines she does have, and the way Jane writes her off after that scene is so bizarre it's absolutely hilarious.
