Well, I've criticized him as being very "basic" in most of his outlooks, perhaps caring too much about presenting an intellectual front, which handicaps him from truly elaborating on any subject with greater insight. He is very aware that his entire reputation would crumble if he adopted positions "outside of the box", so he rarely strays outside of a very controlled narrative.
At times he comes off as rigidly trying to stay "logical" and "consistent" in conversations where there's no real need to stick to an argumentative stance. A man does not always need to try to prove that he is smarter than somebody else, especially when it is pretty clear that they probably are. He's not usually debating rocket scientists, after all (although he may have been doing so here).
Ultimately, I find him to be a man who is too overly concerned with public perception of his work, for someone who claims to be seeking the scientific truths about the world. From what I've seen, I doubt he will be making much advancement in that regard, with the way he is going on about it.
I'd call him more of a philosopher than a scientist, because he's more interested in that which cannot be proven (nor measured), than that which can be.
