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
Once again I was late to the party. I started Swamp Thing with Morrison & Millar's "Bad Gumbo" around '94 (I think?) I had never been into the Vertigo books, I thought they looked a little pretentious and I just liked superheroes. This run kind of bridged the gap, it had some weirdness and artistry while also mixing in more spandex slugfests than Vertigo was normally doing at the time.
When that ended I think is when they started doing the "Essential Vertigo" line beginning with Moore's "The Anatomy Lesson" and there were articles about how amazing that story was. I just remembering thinking "so what?" Swamp Thing isn't really Alec Holland who turned into a plant, he's just a plant who absorbed Holland's mind. Like, what's the difference? He still acts the same. Maybe I'd seen other stories of the type, and like with Dark Knight Returns it didn't play as well for me since I read it too late.
But overall from what I read in the Essential run, they were decent stories. Maybe what I need to do is read the books that came before and see how drastically different they were.
