I always thought that Atlas Shrugged was a neat story idea, rendered into crap. It's a 400 page political treatise wrapped in a 1,200 page book. The treatise is interesting -- most of Rand's non-fiction is very compelling and thought-provoking, in contrast with her largely awful fiction. The story is neat, the characters neat in concept but shit in execution (I mean, seriously, no people are 100% anything, but all of the characters in AS are 100% in their "mode" from the protagonists to the antagonists to the minor supporters, which basically puts them on level with a pulp romance novel or Dr. Seuss in terms of literary quality.)
The Fountainhead was an amazing novel. Night of January 16th was a pretty good play, especially in its expanded form where the audience becomes the "jury" in the trial in the play. Most of the rest of Rand's fiction should have gone where my fiction (and I think most other people's fiction) goes -- in box in the back of the closet, eventually pulled out, reread, chuckled at, and thrown away.
Additionally, although Rand and her cultist followers vehemently denied it, it is impossible for me to believe that Atlas Shrugged was not heavily influenced by the less-known novel The Driver by Garrett (published more than 30 years before AS, it's about a railroad magnate named Henry Galt who almost singlehandedly saves the American economy from meltdown, only to have the government and people label him as a greedy exploiter and try to take it all away from him "for the people's benefit.") Just my opinion, and there's no harm in being influenced by another author -- it's as if the notion that any idea Rand ever had was not something she created from the Eternal Objectivist Ether is blasphemous. Funny stuff, really.
