I enjoyed it a lot. She wrote convincingly, in my opinion, as absurd as objectivism may be. What fascinated me about the book was the character interaction -- they did have a level of believability, but they had extraordinary (in the literal sense of the word) personalities (I'm speaking of Howard Roark, Dominique Francon, and her father) and endeavours (or rather, their purposes for their achievements were atypical). It made them rather interesting. The level of surrealism may be a count against Rand in the literature world, but it's catchy writing, and really, if it makes people read it, more power to her.
