Watchmen is arguably the most important comic book series ever published. There are a (small) number of other books that are (arguably) better, but Watchmen is the one that made the non comic book world stand up and take notice. Other books would not have gotten the notice they did if Watchmen hadn’t made people look. And in a industry where books a month old are forgotten and pretty much worthless, Watchmen has been a best seller for 25 years. Buy why should you own it?
