I have not read this specific work of Benjamin's so I cannot give it five stars, but if it is even close to the stuff I have read, it would certainly deserve them. I've read his brilliant essay "The Work of Art in the Age of Mechanical Reproduction" and his "Critique of Violence"
Benjamin while often dismissed as a Marxist, which he certainly was, combined the ideas of materialism, early 20th century German idealism, and Jewish mysticism to create a unique and complex vision. He was highly influential in the flowering of German literary culture that occurred between the two world wars, although it can be argued that he was as influenced by it, particularly by Brecht, as it was by him.
