I was fascinated by it. But most important to say, I think, is that it wasn't just Alan Moore's. The comic had some of the best art ever to grace a page. Frankly, I think the art drew me in even more than the writing did.
If any are unfamiliar with the comic, here's a brief article - whence came our new banner, as you'll see if you click the link:
Poetry of the Grotesque
My favorite stories involved John Constantine, who of course originated in the Swamp Thing
Back in the early 80s (and late 70s) I was eager to read any comic that had any sort of philosophical/spiritual/ecological themes, and of course this comic was a prime example of such. Between 1976 and 1986 my age was 15-25 and those were my formative years as far as any sort of deep thinking went. Marvel was the first to give me comics that got me seriously thinking, but eventually DC brought in the Brits, in particular Alan Moore, with another great one being Neil Gaiman, and the Brits brought mature (in the best sense of that word) storytelling.
Were you a Swamp Thing
Best and most innovative run on any book I had seen since the early Marvel days. It broke the mold and was, in my opinion, the book that made the comic book world realize the possibilities in none super hero comics. What followed was a golden age for non-traditional comics we still see today-though maybe not to the extent of quality from the earlier period. Of course I can only gauge a tiny portion of output from even the material out there today. It is mind boggling to realize what is available from graphic novel or trade form. I have strayed far from the topic so to pull it in a bit that Swamp Thing run was a creepy and fun time that made me feel like the kid I was who watched old horror movies late at night then hid under the covers-because that would stop the monsters dead in their tracks;}
