While Warner tried to test the waters with a Season 1 Blu-ray, it was too late. Even I, a Blu-ray enthusiast, wouldn't buy a Blu-ray after buying many seasons on DVD. They should have stuck to Blu-ray releases from the start. But that's not what this review is about.
The Mentalist's final season was fine. I was a little underwhelmed by the finale and the way they apprehended the villain, but in hindsight it was more about the relationship of Jane vs. Lisbon.
The quality is fine, like previous seasons. Anamorphic widescreen is fine although with hi-def broadcasts, I'm still wishing for Blu-ray releases on TV titles. 5.1 surround sound is adequate for a TV show.
Extras are fine as well.
Even though I didn't go into detail about extras and A/V quality, the main reason you'll get this is to complete your collection of this fine TV show.
