Ayn Rand was a pretty terrible person. But you’re right that there are some interesting ideas in her books. Howard Roark in The Fountainhead is exceedingly interesting as a person living genuinely without much regard for societal norms and expectations. There’s some weird stuff in that book, but Howard Roark is very interesting. A trimmed down version of The Fountainhead would be much better received, I think. (It’s over 700 pages and has some odd and unnecessary scenes where some of Ayn Rand’s less-than-great views probably shine through. It would also just benefit from some good editing.)
