I don't want the next Batman movies to follow the Sherlock Holmes movies ; Batman should be blazing his own path, not giving cinema audiences something they've already seen for the sake of a supposedly more faithful interpretation.
We've had Burton give dark, gothic fantasy, Schumacher give family-friendly, schlocky adventure and Nolan give deep, epic realism.
A direction I'd like to see is high-octane, high-tech flashy superheroics a la Morrison's Batman and Robin with a background of Gotham history and family feuding a la Gates of Gotham. Something that really builds Gotham as it's own entity rather than a faux New York\Chicago.
I'd make the Court of Owls and the Penguin as their leader the antagonists in the first movie. They'd help answer three important questions about Batman's place in Gotham.
1) Why is Gotham a corrupt, crime-ridden city? Because the Court likes keeping it that way for its' own benefit.
2) Why would Bruce Wayne choose to fight crime in Gotham? Because it's his home city and one the Waynes have striven to build over the generations while the latest scion of the Cobblepots wants to screw into the ground.
3) Why would Bruce Wayne dress up as a bat? Because the Court and its soldiers have adopted the owl as its symbol and he needed to create a bigger, bolder and more terrifying avatar for his war against them.
2nd movie would be loosely based on Knightfall and Year Two with Batman going up against an ends-justifies-the -means brutal vigilante, the Reaper and his daughter the Huntress who could probably segue into a love interest and end the movie by becoming Batwoman.
Third movie would involve the Riddler and Shiva and introduce Robin.
