After 7 seasons, CBS decided to pull the plug on The Mentalist, the Simon Baker/Robin Tunney vehicle, following an abbreviated 13-episode final season.  The show, which was a strong performer in its earlier days, was obviously out of steam creatively in its last few years.  The show got a bit of a reboot last year, during season 6, when the setting and motivation changed, but it wasn’t enough to breathe new life into the tired show.
