Let me boil it down for you:
All the good guys have neat names, are beautiful, smart, and enjoy violent sex (which they consider to be a philosophical statement). They have no apparent sense of humor, but do seem to enjoy venomous discussions of money and cigarettes. Everything they do is perfect. They can and do invent calculus at an early age.
The bad guys have awful-sounding names. They are rather shapeless, stupid, greedy, and envious in nature. They are liver-lipped, have ugly, watery eyes, and if they are female they wear things like knee-socks. Sex (if they have it) is apparently based on mutual loathing. Nothing they do ever works, except somehow they have always been able to outsmart the smart people.
To be honest, I used to think it was a great book. I read it about 10 times. Halfway through #11, however, I realized that it is not a great book at all. It's dull. Its characters are charicatures, and not very good ones, at that. Ayn Rand's ideas about sex are simply ludicrous.
For a classic review of the book by Whittaker Chambers, go here. It's about half-way down the page.
