Curious if the film will retain the book's ending
The novel was a fun, quick read (reminded me of the type of scientific-thriller fiction Michael Crichton used to write). Not great, just entertaining.
[spoiler]: I'm curious, though, if the movie will have the guts not to change the ending of the book, which ends somewhat pessimistically for Emma Watson's character. It echoes back to the granddaddy novel of all dystopian tales--1984--in the way that its main character is basically broken and submits to the will of the ruling powers.
Seeing as how this is a Hollywood movie, if I was gonna bet on whether it does or not, I'd say it won't end with a downbeat ending, but one that at least introduces some hope into the tale.
