It perhaps is why I am struggling with Batman/Superman World's Finest #26 and this imp arc. It just hasn't grabbed me yet. It is a weird mix of fun and dark, perhaps not enough of either to make me feel settled. And being an unsettled reader isn't a bad thing. I'm thinking about this story a lot after I have read it. There has always been a sort of sense of joy or reverence with the DCU in this book and I'm just not getting the joy.
Mark Waid has a decent idea here. If there are imps obsessed with Batman and Superman, couldn't there be imps obsessed with Sinestro and the Parasite? And having the World's Finest teams split up with their opposite World's Funnest team is a good story beat. But there is a darkness in this story that bubbles under the surface.
Meanwhile, Dan Mora continues to just bring it. From the zaniness of the imp designs to the psychedelic insanity of Parasite's attacks from a nod to classic Earth-2 Robin, he stuff continues to be the best artist out there.
On to the book.
