My thoughts on this come from my reading of the current Animal Man/Swamp Thing crossover. As things got underway I quickly realized that the only way that this story could end was with time travel that made sure that all of the events that I was about to read would never actually take place.
I was right as the end of Swamp Thing #17 Arcane went back in time and Animal Man and Swamp Thing followed him.
First off, I do have to say that I have enjoyed Rotworld so far and that overall it's been alright. Having said that, is anyone else a little tired of reading, watching or hearing stories with this sort of ending? Yeah it can be done right, but too often, personally speaking, I get the feeling in the middle of the story that nothing I'm seeing, reading or hearing matters. That's not a feeling that enhances the experience.
