I've read some of his stuff too, and I've seen him being interviewed several times, but I don't know what to make of him either. He's by no means an unintelligent man, and there are moments when he seems quite lucid - but when he talks about his famous reptilians he gives the impression that he's lost the plot completely - and actually, I think he has.
For anyone interested in reading more, here's a link to his website.
