My overall rating of "The mentalist"'s Season 1: 4/10.
This episode has an IMDb aggregate score of 7,3, making it the lowest-rated of the entire series. I don't always agree with the public's scores, but in this case the public's not at all off the mark - although I do wonder if it's quite fair to count this episode as _the worst_ - even in just Season 1 there have already been some really bad ones, there's stiff competition.
In addition to some of the series' usual bouquet of flaws, this episode is essentially "The mentalist goes Hollywood" which is fairly lame for a theme, and it isn't really developed in-depth anyway. It reminded me of "Bosch" with its Hollywood precinct (or whatever it was), and it isn't so often I recall "Bosch" fondly. The senseless overload of melodrama, the contrivances, CBI just refusing to charge any people with any non-murder crimes at this point, questionable acting...
Interestingly, the agent isn't played by the guy who played Mike in "Veep", even though they look fairly similarly. As for the episode's strong sides, I guess the mother/actress character is pretty, but that's about it.
