I expected a little less action and a little more conversation. Hoped for a subtile mindgame to catch Red John, not a bloody war.
Blowing things up brutally, that's no real Mentalist-style. And then, to see a piece of Bret Stiles' body, the master himself, laying around like garbage, it hurts in all its rudeness. Maybe I'm judging too fast and they recover things in next episode...

If Bertram is Red John, and it looks like that, then maybe this was a clue after all, when at the mall he told Jane to seek help, a psychiatrist, and that he knew excellent doctors (e.g. Sophie Miller).
