I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
I normally enjoy Gaiman's stuff more than I did this: it felt disjointed in a way that was abrading. I just wanted it to end by the midway point.
The story about a man dying interposed with his fantasies of his last, greatest movie - the one he hasn't made, and probably won't have time to make. Except the beginning is all about hackers and I have no idea what connection it had to the main story. The poetry in between chapters made sense in a way, but I could have lived without them.
The real reason to read this is the art, in my opinion. The art is amazing. Beautiful, emotive, diverse, and it just held this whole narrative together.
