Henri over at The Philip K Dick Bookshelf links to this review of A Scanner Darkly.
"...I see a failing [in the movie] that is sometimes attributable to recreational narcotics: an unfortunate tendency for the imaginer to apply too much profundity to their personal hallucinations."
And then, only two paragraphs later writes:
"I'd like to see A Scanner Darkly "unanimated." All in live action film, with CGI effects for the scramble suit, and the animated technique reserved to show life through the eyes of someone on Substance D."
Duly noted Webomatica, you do not believe personal hallucinations can communicate a narrative effectively -- unless of course it is your personal hallucination...
