I got into a "haunted media" phase last year and recently re-read this.  (There are two digital versions of this, and somehow, through various bundles and sales, I ended up owning both. Not sure if there's any differences between them.)  I didn't remember liking it as much as I did this time.  I think I connected more with the main character, a film history professor who faces an autism diagnosis for her son and a loss of her job, throwing herself into the obsession of a long-dead (?) film pioneer and their experimental, untitled works, in part to escape the feelings of her present circumstances.  Yet those circumstances follow her throughout her journey.  As she teeters at the edge of cosmic madness, she also finds new facets to relationships, new sides to herself.  I remember disliking how some of the characters turned out to be my first time through - this time, though, I started to understand how these are just new sides to the characters.  This book is not a movie - thank goodness.  Highly recommended.
