This was a very interesting end. I've noticed when some of the previous New 52 series ended they either were a celebration of what they are (Frankenstein), provided a bit of retrospection (Animal Man), pull out every card left (Dial H), and/or provided a sense of finality for its story while leaving it open for new ones to be told (I,Vampire, Lemire's Green Arrow run and Snyder's Swamp Thing run). Here we get almost a mixture of everything. The Machine storyline is wrapped up, Etrigan is brought in referencing the third Annual, Arcane is still on the loose, the Grey is left without an avatar, their is meta-commentary of the entire New 52 run, and more.
I thought it was very well done. I thought the twist and commentary were well done and was more a thank you to the fans that have stuck with this series. You can tell that Soule has a tremendous amount of respect for all the writers that have worked with the character and now he finishes leaving his mark. The art team was on point the whole way through. Kinda wish their was something more with Holland and Abby at the end and kinda wished for a last minute surprise back up by the Red who were surprisingly absent when all the other kingdoms are fighting each other. Still the series ends with a feeling that it'll come back. Maybe it'll be relaunched or maybe we'll see old Swampy again in Dark Universe. I really wished for the series to have been a bit longer just so we could have gotten a Bacteria arc as I loved what Soule did with that in the Futures End issue and now I see why he dedicated a good part of that issue to that. Still its yet another piece that Soule leaves for another writer to use or not use if and when the big salad comes back again.
Out of all the New 52 that have ended, this is the one that I just want more of because their are so many ways the character can go and their are a number of different writers that can take a stab at him as opposed to Dial H where I felt that I probably wouldn't have been comfortable with anyone continuing that other than Mieville. Hopefully the wait to see Swampy again solo or as part of a team isn't long.
