Kill me now.
The only hope is that, like the Wolfgang Petersen World's Finest, Batman vs. Superman, this too will be aborted before shooting commences.
At this point, why not just start with Vibe and Gypsy and Vixen? Or, hell, why not start post-Justice League, with Batman leaving in a huff and starting the Outsiders, which is a much more manageable group of heroes (who could, with the right handling, turn into their own franchise). I always thought Batman and the Outsiders would make for an interesting 115 minute movie.
