I am a very simple man: if I see a crossover between somewhat recognizable characters, 95% of the time, I will enjoy it. And while the game this is based on died before it could gain any traction, I got a tinge of seratonin seeing some wacky characters be in places they should not be.
That lil hit of happiness doesn't last long as they kinda lampshade it on the very first page on the very first issue: WHY? Lotsa cosmic shenanigans and multiversal mumbo-jumbo's involved, but overall, any port in a storm of nonsense. It's the false advertising and knowing the story will never be completed that gets it for me. False advertising because despite some of the covers, some classic recognizable faces under the WB umbrella DO NOT show up in the way you expect (robot drone facsimiles; a particular mad scientist invisibly controlling another character with a WUB A LUB DUB, etc) or not at all (Gizmo the Mogwai could've been the substitute for the OC critter and nothing really would've changed!).
But yeah, the humor is a highlight, the action is wacky, and most of the time the characters are true to form. And even if it ends on a To Be Continued with no hope of it actually concluding, it's still worth a look if you wanna see Bugs Bunny play off of Batman or the Wicked Witch of the West tussle with Wonder Woman in Gorilla City.
