A few good ones here amidst mediocre stories. Nightfall is overrated as “the greatest sci-fi story”. Asimov is a bit over-rated too, I dare say; a bit full of himself, anyway. I only say that after having read most of his fiction.
At the time, I suppose it was cutting edge but he was so clinical in his approach. His writing was methodical, not highly creative. Take planet X, alien Y, spaceship Z, and throw a couple humans into the mix. Re-shuffle and there you go with another one.
