I second the Bad-Dad vote. Like Wolverine, Bruce is infinitely more interesting when he is not doing his entire loner thing. Some of that is nice, but mainly as contrast.
Particularly, I want a movie that has all his kids sort of skulking in the periphery until some grand conclusion has them all come together and 'Manoeuvre seven' some fools.
Preferably post-Under the Hood. I want Jason around, but I am not sure I am ready for an adaptation after Arkham Knight.
Meaningful cameos from the greater universe would also be nice. Enough to remind us that Batman lives in a shared world, but not so much that it overwhelms the movie.
