I'm not going to bother commenting on the content of this DVD, because even I feel it is an insult with all the errors and factual mistakes. First the most annoying error -- he has a group sitting in one room talking about the Holocaust without noting that almost every person who ever worked for or was persecuted by Nazis was Jewish, making no distinctions at all: they were all Jews.

I have purchased this product before and it tasted fine, however, the last two times, something was not quite right. And sure enough, my third container also left an awful metallic taste behind it. I gave one bottle to a friend who had similar problems, then decided that we should throw them out. That is what I did. Too bad because they are good tasting.

I was so excited to learn the latest incarnation of Robert B. Parker's wonderful detective series had recently entered it's second season....boy am I disappointed! In Season 2 we get the return of Harry Bosch. A man who may be as evil and dangerous as ever but still somewhat likeable, which is why there is a chance that he will turn out "bad". But Bosch has absolutely no reason for being on this show; at least nothing interesting about him. I don't know what happened here.
