Well he actually mentioned the Lord of the Rings books and Hobbit. And of course Harry Potter.
But I think that is it. I am personally not touching this too much because I do not want to be the pot who calls the kettle black, as most of the books I read are either related to Stephen King/horror in general, a few dystopians or by Terry Pratchett.
That said, even if similiar to Dobson I enjoy immature entertainment more, I think I can point towards some better stories that he should at least in some form know about. Not because they are must reads for everyone, but because of his supposed profession. Example: V for Vendetta or Watchmen. Has he ever talked about stuff like these? I find it at least weird that someone who considers himself a professional comic artist is incapable of making a statement about them that does not sound like out of the mouth of a sjw post 2011.
