It's no secret that "Bladerunner" departs widely from the book it was based on, and that probably kept me from getting very far into this book back in the 1980s. 
 Having just finished it, though, my thoughts are more like, "Screw Bladerunner." 
 I loved the Deckard's argument with his wife about her scheduled six-hour self-accusatory depression. I loved the discombobulating interview with Luba Luft even more. 
 When things literally start falling apart toward the end (or is Isidore imagining things?), I even like the visions granted to the main characters. I put the book down genuinely moved, which I realize is a lame thing to say.
