I think that is a spoiler, can you remove it?
To anyone who reads Cloud Atlas, I strongly recommend you also watch the movie, and vice versa.
But I wasn't really bothered that some of the details hinted at in part 2 were hand-waved away as "other stories." I'm really not a fan of sequel-itis and I appreciate Stephenson doesn't go in for it. I'm fine with not every backstory or thread being fleshed out in detail.
They completely defeated my suspension of disbelief. It was the way a 6 year old would have predicted the result.
