I have posted a review of this on my blog, The Itinerant Librarian. An excerpt from the review:
"This is one that I truly enjoy. When I think of a good action comic that is not overly complicated and just fun reading, this will come to mind. Matt Wagner brings the origin of the Green Hornet to life with a good story, and Aaron Campbell's art is great as well capturing the 1930s era well in terms of color and ambiance."
