I started reading Swamp Thing from the very beginning... sort of. When I was a kid, I liked superhero comics and not much else (no western, no war, etc.). I also gravitated toward Marvel, so Swamp Thing had two strikes against it right out of the gate (to mix a metaphor or two). I remember seeing titles such as Swamp Thing and Kamandi on the spinner racks but not giving them a second look (or even a first). Even when I walked into a comic book shop for the first time in my life several years later, it took some time for me to overcome my preconceived notions regarding such titles as Daredevil (Frank Miller's) and Swamp Thing (Alan Moore's). Then, in 1986, DC released the Roots of the Swamp Thing reprint series and i started at the very beginning (#1) if not exactly from the very beginning (1972).
Skip ahead 15 years. I'm now married. My new bride is not wholly unfamiliar with comic books and is willing to read more. I recommended a list of 8 or 10 of my favorites (including the Wein/Wrightson and the Moore/Bisette/Totleben runs of Swamp Thing), most of which she read. I had tens of thousands of comics in my collection at that time, enough to keep us busy reading and discussing for years. But she became interested in comics I didn't have, such as the post-Moore Swamp Thing as well as the complete run of Fables (which I myself still have not read). We spent the next however-many-it-was months collecting backissues of Swamp Thing plus I added those two titles to my pull & hold.
At this point Tracy has read literally hundreds more issues of Swamp Thing than I have. We don't have every issue (she finally lost interest after the "New 52"), but we have quite a few. Ironically, it was "Brightest Day" which reignited my own interest, so some of the more recent issues she has not read. I like to "prorate" the cost of my comics by a) reading them multiple times, or b) giving them to my wife to read. We get the best value from those comic we both read multiple times. To that end, we have decided to work our way through every issue we own from 1972 to 2018.
We recently led a discussion through every issue/series in Terry Moore's "SiP-verse" but, if we complete it, this project is more than twice as long. We invite you along for the ride.
