The third season of the Mentalist continues along the lines of the series - a fresh approach to crime with none of the now typical high budget high tech forensics, cops dressed like high society celebrities or scenic helicopter shots of the surroundings. Patrick Jane (played by Simon Baker) is the ex-medium turned police consultant, who uses his acute powers of observation of people to solve crimes.
The Red John mass murderer case continues to hover in the background but is less defining than in the first season - the scene for it has already been set and the third season works on developing the relationships in the CBI team further. The chemistry between the actors continues to exist, in spite of the semi official relationships being off. This allows the writers to delve more in the characteristics of the cast, which make the series continuously engaging.
So if you are looking for an amusing crime show, where the protagonists often bring a smile to your face (not that the crimes would, don't get me wrong) the Mentalist is still hard to beat, even in the third season. And the introduction of several new, colourful characters, all in some ways related and complementary, keeps things interesting.
Whether Red John gets caught, well, dive in and find out!
