The problem is that most of the mainstream audience would find real science fiction boring-- when they think of science fiction, they think of monsters and explosions.

I've heard nothing but horrible things about the sequels and I must admit, I've read them... while they lack some of the magic of book one I found them enjoyable... I know I'm waaaay in the minority on that one. I especially liked the parts at the Raman node and the refurbishing of a Rama craft...
I enjoyed them, too, in the same way that I enjoyed the second Foundation
trilogy-- well done, but inappropriate and inconsistent with the real thing.
