Historically, Alan Moore's Swamp Thing is one of the most important comics ever published. It brought to a wide audience, most particularly including other comics creators, that it was possible to create an intelligent well-written and literate commercial comic. It was a wake-up call that comics really could be good. So it's a shame that in these days of super-duper special editions that DC have chosen to reprint these stories in such relatively shoddy editions. Aside from the fact that they are more durable hardbacks, the paper quality is little, if at all, better than that of the original comics and the pages are of standard size. This current volume only contains 6 stories. No new introductions were commissioned, and instead we get cobbled-together reprints of introductions to previous editions. In this current volume, two intros have been edited together by the original author. Wow. It's worth comparing them with the Starman omnibus editions which are done right.
This is all particularly annoying because these 6 collections (as of this writing, one more remains to be published) are essential purchases. The stories, the writing, the artwork are all wonderful classic comics which demand to be any remotely decent collection. So get them now because lord knows when they'll be reprinted again.
