This movie looks really cool just by the way it's shot with that weird animation style. Philip K. Dick is a great writer, I loved his other book The Man in the High Castle which is this bizarre book that talks about america being split up in two by germany and japan after they both had won world war 2.
The plot for A Scanner Sarkly looks really good too: a bleak mixture of science fiction and
police procedural, in which an undercover narcotics detective ingests massive amounts of a dangerous drug in order to maintain his cover.
