I was reading Golden Age SF while the rest of you read comic books. ACC was never that good on characters but he could write a stunningly good short story. Definitely the end of an era.
I'm with you, Louise. The comics weren't bad, but the books were better, ACC's among them.
I think I read both and saw the film at approx same time.Kirby was a better director than Kubrick. And his characters had more believable ranges of expressions.
