I have been curious about the Swamp Thing before but it wasn't until some friends recommended me specifically the Alan Moore run of the comic that I decided to actually go out and give it a shot. Though I wasn't able to get the Moore comics at the time and settled for this omnibus instead, collecting the original 70s run by Len Wein and Martin Pasko's issues of the 80s revival over whopping 900+ pages that I blasted through in a month to make the library deadline.

Wein's original series was a mostly fun but chaotic romp, jumping around wild scenarios with each issue, many of them too brief to really get to the interesting parts of the concepts. Also, there is barely any actual swamp in the first 10 or so issues which was kind of funny but also a bit disappointing to me, considering this whole series is literally called Swamp Thing.
There were still some neat ideas and good art, and past the first 10 or so issues, the story does get a little bit more coherent between issues to make it a bit more engaging.
The revival run of the 80s called Saga of the Swamp Thing, helmed by writer Martin Pasko, was a blast though especially after reading it immediately after the originals. Because these issues were much more coherent between issues, actually trying to tell a bigger, overarching story, and Pasko manages to bring back concepts and characters from Wein's comics in much more interesting ways. Additionally, there are some amazing creature designs by the illustrators in here.

All in all, this made for a good look at the beginnings of this DC character and seeing the development from Wein to Pasko was actually really interesting.
But now I'm extra curious to see how this series developed once Moore took over since it seems to me like his take on Swamp Thing is considered the best one and Pasko already did some pretty great things with it.
