Have the 1st season on dvd, and the hosts seemed to know their stuff.
Granted, I've taken a class under Rob Pincus and due to his computer being murdered, now have a round dozen of his training DVDs.
So I really respect his philosophy on defense.
He was a host for I believe seasons one and two?
I haven't seen the show since he left, but I'm sure they continued to present the situations with the same integrity.
I recommend to first season at least, and have few doubts I'll feel the same about the others after I've seen them.
I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain.
