Saw it Saturday. Id have sat thru 10 hours more.
Same here. I was surprised when some people said it was hard to follow if you hadn't read the book. I haven't read the book and I was able to follow it quite easily. It just took a little time getting used to the future speak, but even that became second nature after a while.
The narratives themselves were actually pretty straightforward, and it wasn't hard to keep track of them at all.
