Here's a list of some of the folks who have written Swamp Thing over the years: Alan Moore, Len Wein, Scott Snyder, Brian K Vaughan, Joshua Dysart, Rick Veitch, Grant Morrison, Mark Millar. That's not even a full list, but you see my point - ol' Swampy has had some seriously brilliant people behind the keyboard in his time.
I was an enormous fan of Dan Slott's run, and John Byrne's run was a big deal for me. I found Slott's version of 'She-Hulk' first, and then I went back and looked up some of the older stuff because I liked it so much. And it was so good. It was perfect. It was my perfect comic book at the time that I found it.
