Vaughan's writing is excellent--realistic, entertaining, character driven, thoughtful--and the art is also top notch. It is easy to see why this title won multiple Eisner awards. Its realism also brings some adult content with it that potential reader should be aware of. There are a few instances of blood and sexual content, but my main concern was language. There is a large amount of profanity (which may be an accurate depiction of how many people speak), but I found it excessive to the point of distracting from the story at times. Maybe if all the characters didn't speak that way it would make more sense to me. Also note that this volume only contains part of the story, so some plot threads are left to be resolved in later collections. This just left me wanting more, but if you're looking for a short read, you may want to look elsewhere. This book collects issues 1-5 of Ex Machina, and the total story is 50 issues long. I don't know if I'll read the entire series, but I will definitely read at least one more book.
Despite any flaws, the art and story are very compelling, providing a unique and current look at super heroes and current events. If you like comics and graphic novels, are comfortable with the mature content, and want to read one of the more interesting and relevant modern series, this one's a must! I give it a Definitely worth checking out.
