In my honeymoon period with Buddhism (still not finished?), I was hypnotized by Ajan Brahm's talks, probably due to his slow alpha wave talking. Due to the availability on the web I tend to listen to many of his talks. The more I listened, I found that he brag about himself and disparages others mentioning their names. At a public talk given at Gaia House, Ajan Brahm criticized couple of other ajans for playing politics. Also, once he criticized Professor Peter Harvey about a meditative claim saying, "what meditation he knows!"
The person who broke me from Christianity was Krishnamurti, his teachings made me think differently. Here http://www.youtube.com/watch?v=hQSBFC_IlVY
at the end of the talk Ajan Brahm even look down on him.
IMHO, for a famous teacher like Ajan Brahm, it's more conducive if he simply mentions a situation without names and compare it with a Sutta pointing to the faults. That way people will gain more faith in Buddhism and the way Buddhists deal in real life.
One teaching Ajan Brahm repeatedly talk about is not to find fault with others. At least he should practice what he preached.
