Denis Murphy writes- I've mentioned before that when growing up I wasn't really into comics. I'd enjoy the odd Spider-Man and X-Men comic here and there, but never really saw it as a hobby. Still though, even without reading comics regularly, I at least knew about the big dogs in the comic-book world. From Green Lantern to Aquaman I had a general sense of who everyone was. However, one group of heroes I never heard of up until around two years ago were the Guardians of the Galaxy.
