Maybe. A lot of the older classic authors have their downsides in how they write their books, and if anything I remember Heinlein's women were not that great. I liked some of their traits, but they were in the end shallow. Fortunately modern writers have evolves, right? :/

The ending of NotB was so off for me for whatever reason that I can't really remember it. I can remember other books of his pretty well. Must mean something. But it was the initial concept that got things going and some of the early character stuff that I liked.
