I feel the stories got successively smaller from 2010 and on. 2010's epilogue hints at the developments after 20,000 years, and 2061 and 3001 feel small in comparison.
2010 is a good follow on to the 2001 book, and answers some of the questions the first book left while expanding the mysteries and the sense of wonder.
My wife and I still quote it when answering questions such as what's for dinner.
"Something wonderful".
