Overall I have been enjoying it. There have been a few episodes where I thought they either under or over emphasized some things, but it is a pretty good. They do have a tendency to explain things in a way that is questionable. That is they don't mention other opinions on some subjects so that the science is presented as settled, when there is no real consensus. This episode is the worst so far.
