Not optimistic, but the idea of setting up an epic clash between supes and bats, and having Wonder Woman show up, and setting up the Justice League, and presumably actually having some sort of villain all within a 2-2.5 hour movie seemed liked a silly plan.
And I've said many times these kinds of things should be made as serials. Costs a lot to put together a team, make sets, and then mothball everything, only to come back to it a couple of years later. Take a year, make six 2 hour movies, release one every 4 months.
