Also check out the book (not the movie) "Non-stop" by Brian Aldiss. The first 2/3 of the book is meh - uninteresting characters, motivations, a bit above average setting. Then it really takes off and you see the writer hasn't been wasting your time. Also The Book of the New Sun by Gene Wolfe. It's much slower paced and more about the mood and immersion.
