I've only just started reading PKD, with
The Collected Stories of Philip K. Dick - Vol. 5. I've read just 8 of the stories, but Connavar asked for my impressions, and this seemed like an appropriate thread. (I don't have Vol. 1, Conn, I borrowed this one from the library.) I checked out this collection as an intro to PKD, just to make sure I'd like him before jumping into one of his novels. Needless to say, I'll definitely be jumping in.
My favorite so far is
Retreat Syndrome. Very interesting concept, and very well told, with plenty of twists for so few pages. I'm sure I'll add some favorites once I finish the collection.
These stories make me feel like I'm reading Twilight Zone episodes. In fact, someone with some creativity could make quite a good TV series out of his stories. As soon as a creative type gets hired for television, maybe it'll happen.
It's called
Not by Its Cover.
