"In his short career, Stanley G. Weinbaum revolutionized science fiction. We are still exploring the themes he gave us." —Poul Anderson
"Stanley G. Weinbaum's name deserves to rank with those of Wells and Heinlein—and no more than a handful of others—as among the great shapers of modern science fiction." —Frederik Pohl
This was an extremely fun read! All the short stories contained in this book were entertaining and imaginative, it wasn't perhaps the most coherent or cohesive of collections but the sci-fi theme was mostly present, so that's fine.
Weinbaum's forte decisively is worldbuilding, his imagination and creative vision as he describes Mars and Venus through their environment, flora and fauna, together with the political stance of the colonizers, though it suffered the passage of time slightly, is unparalleled, tremendously vivid and genuinely funny, and it is supported by a narrative style that manages to be very thoroughly descriptive without sounding like a scientific or zoologic textbook.
