The only complaint about this book is that the stories are sometimes so short that the characters cannot be developed. But the themes are excellent. Like poetry, just the skeletal outline of the plot will please you. Three of my favorites (relying on memory, I read this book years ago) were A.C. Clarke's story of the haunted space suit, "Columbus is a dope" by ? (both ironically comical) and the provocative "hunted aliens". I think the excellent "Time Machine and Dinosaur Hunter" story is in here too, but I'm not sure.
Also read Jorge Luis Borges "Labyrinths" (one anthology) for a better treatment of the same theme (short stories with a sci-fi element).
