This is a warning to customers who might want to purchase the next 3/4 hardcovers: Don't get greedy.
Listen, buy this book. It collects the first three trades, and its amazing. You could say this about the next collection, too, I bet. However, as the series races towards its predetermined deadline (100 Bullets = 100 Issues, for those not on wikipedia), the story moves so quickly that its like watching a cartoon rocket car... Every MPH faster, it loses another integral part, the paints tearing off, the entire vehicle is shaking, and by the time it crosses the finish line, its just you, holding a book wondering "Did I really just spend all that money and this is the ending?"
Trust me. I've been there. I bought the series. I read it. And its a fast read. The action is fast. The drama is fast. The artwork is fast (and by fast, I mean, "I hate the artwork, but it does the job). But by time we get to the end, half the characters look the same, talk the same, you're not sure of the actual plot, but the "big picture" set up is so unreal that you'll just have to shake it off as, "Whatever, I know its a comic, let's get back to the small picture" which is where the best writing/stories take place... And still, like I said, at the end of the series, I was just scratching my head... Really? This is it? Ok. I guess that was fun while it lasted.
So don't get greedy after reading this volume. You'll enjoy the hell out of it. Its the best in the series. But if you want more than what you've got in this hardcover, then you're only going to disappoint yourself.
