I have no idea who this person is, but I assume he had something to do with the film. If that's the case, I just can't imagine how he could say those things with a straight face. Does he really take himself that seriously?
It was a movie.
Both are not your fault. But perhaps you should do some research about who he was before you choose to have an opinion about him.
I prefer to read things I see here without any context or preconceptions. I'll often get to the bottom of an article or all the way back to the comments here before I discover it was written by somebody I'm familiar with. I thinks that's helpful because it keeps your mind free of bias while you're soaking up what's written on the page.
I'd suggest reading the letter again without any preconceptions and see if it seems a bit self-important.
Apparently not as much as you think if you don't know who PKD is.
Speaking of which, Powells itself is a full city block, 3 stories high, with a Technical Books annex filling another half block. I'm reading as fast as I can, but you'll have to cut me a bit of slack for not getting around to this particular author yet.
Any suggestions for a title I should start with?
Go for quality, not quantity. Remember, 90% of everything is crap ... and I hope that you get that reference.
If you don't know what you're talking about, why speak?
When he saw Ridley Scotts's work on the visuals of Blade runner he was amazed. Remember before this, and Scott's Alien most SF films consisted of putting the star in spandex and drapping the set with some tin foil.
This is especially gracious since Blade Runner takes one tiny part of a complex themed book and turns it into little more than a cop chase. He might have been less impressed with some of the later recreations of his books.
