I regret that I have to write in English as my Chinese writing board is not around. 劉燦榮 is one of those celebrity commentators in Taiwan whom I have a lot of respect for. He does not talk baloney, what he describes are factual information. Indeed, it would be nice if it were free of charge, but to be honest, everyone has to make a living, and there is a cost for quality production. Two comments I would like to make, (a) I would have hoped he will talk about ancient China also, he is VERY GOOD at that, and (b) have a little more visual effects as opposed to still pictures only. That would improve the quality of product, but then, I appreciate that, again, there will be cost involved. It is expensive. This is a very informative production, very good.
