I could never get into it because of his personal beef against veganism (no pun intended).
I think it started when the guys who made Cowspiracy went to his show. After that he went on a mission to find every piece of pseudoscience or blog post that said the animal industry is actually good for the environment, or that plants have feelings, or that vegans were unhealthy, and then went on a Twitter rage against vegans.
It was pretty clear that his open-mindedness was quite limited. The sad thing is that a lot of people think he is a reliable source of information.
