I am intrigued and have (tempered) excitement for this iteration, based on what Reeves has said (noir thriller). He nails it with his assessment of TDK (one of if not my favourite CB movie ever), that it is basically a Joker movie. Waititi on Thor 3: There's no point calling the movie Thor if he's not the coolest thing in it.
Reeves has mentioned he will focus on the detective aspect of Batman which has been sorely neglected in his cinematic appearances. I hope they write a movie where Batman is the smartest thing in it, and the mystery that unravels is a surprise to the audience. Write the screenplay in such a way that this is focused on and every time the viewer makes a deduction, Batman should have already been there half an hour ago.
Finally please use the Batman we saw in BvS as the baseline for his fighting ability. WB, I know you're not listening, but make Batman invincible against (groups of) low level thugs, he's earned it. Anything capable of giving him a challenge in a fist fight should either be one of his deadliest foes or a metahuman. If BvS did one thing right it was capture the essence of Batman's fighting style visually based on the combat system in the Arkham series.
Without having to add a single scene for a shared universe, you can plant a seed by making it obvious he's the smartest person in almost any room. When you inevitably see this Batman in another Justice League movie, you will have faith that this version of the hero will have a plan to save their metahuman butts when it hits the fan.
This might seem like a silly thing to really need in a movie but I want a movie that celebrates the fact that Bruce Wayne is exceptional, he would have to be.
