Well, that was unpleasant.
The premise of this story is built around multiple Supermans and Clark Kents running around, which has been something that's been confusing me in every Superman Rebirth title I've picked up to date. Some of that gets cleared up, but there are a number of plot threads that are heavy in the first couple issues covered by this collection that are just abandoned as it goes on, leaving me wondering why they were included at all. Also, the story involves one of my least favorite villains in the DC universe (because he's really annoying), Mxyzptlk. So, this was confusing, annoying, and failed in terms of story. Definitely a dud.
