Rendezvous with Rama

I was intrigued at Rama at the beginning of the book. As the book went on, my interest waned considerably. Characters have no development or arcs, there is some blatant sexism in the writing that is a big turn-off, and the world of Rama is just not that fascinating. The science is well-explained and thought out, but I had not interest in the people or events it was affecting. I was bored, and rushed through the end just to finish it.
