It was a solidly popular venture that lasted for seven seasons, but the axe finally fell on "The Mentalist" in 2015. Why? It seems the show's death can be connected to a downturn in the show's ratings precipitated by fake psychic turned real police profiler Patrick Jane's (Simon Baker) finally tracking down the man who killed his wife and child, Red John, during Season 5. In the wake of a villain reveal that would turn out to be devastatingly underwhelming, Patrick subsequently began working for the FBI during Season 6, and audiences weren't up for that big narrative change. This caused a further slide in the show's ratings, which had already been on the ropes since Season 5, where it went from 14.22 million viewers for Season 4 to 11.06 million.
