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
I have the few issues featuring Superman and Batman, but nothing else.
I've looked through the tpb's (and the art is amazing), but I can't quite get myself to buy them and delve in.
From my very cursory impression, it seems like an extended hippy-dippy meditation on the environment or somesuch, but I'm sure that's an oversimplification. Like I said, could never make myself delve in.
