Sure. Lots of people though I’m not one of them. Don’t much care for his juveniles and some of his later books were real stinkers. But, overall, with books like The Moon is a Harsh Mistress and Time Enough for Love I have to give him a lot of credit even if it requires a certain dose of historical perspective. I did grow up with him to some degree. I wouldn’t really expect someone reading Heinlein for the first time today to have the same reaction.
