As one of the grittiest comic heroes, Batman is called "The dark knight" for a good reason. His morals keep him from losing track of what he stands for, so he treads a thin line between hero and villain. Those who know the character know how much of a hero he really is rather than mistaking him for an anti-hero or a rich man beaten up by poor people.
However, the best way to explain a superhero like Batman, who can strike fear into even the hardest of criminals, is to show how difficult it is to be that hero. Matt Reeves is no stranger to horror films, having worked on Cloverfield and Let Me In. As director for The Batman, he is doing everything he can to make Batman terrifying.
The Scariest Batman
"This movie, I think, is probably the scariest Batman that has been done because the idea of what Batman's doing—it's scary." Reeves said in an interview with Total Film Magazine. Batman is the most frightening superhero in the eyes of villains, not because he will save the day, but because of how he saves it.
Usually, Batman carries business cards and cash to help villains who are only doing their best to feed their families. This is why Wayne Enterprises hires so many ex-convicts. The rest of Batman's gear is meant to stop villains in other ways, both physically and mentally.

According to Matt Reeves, Batman has "never been done in quite this way. It's a detective story, it's an action movie, and it's a psychological thriller." Matt Reeves does not want to adopt any other story, he wants to show Bruce Wayne's struggle to become Batman and how he gradually transforms into the hero.
Robert Pattinson will play Batman in Matt Reeve's The Batman and had this to say at DC FanDome:
"He hasn't completely defined what Batman is. I mean, he gets lost in it whenever he's putting on [Batman] every night. He's not sleeping and he's becoming this quite sort of odd creature…"
"He doesn't have as much control over his personality, like the delineation between when he's Batman and when he's Bruce is not so clear and other kinds of iterations of it where he really knows what he's doing when he's putting on the cowl. And I kind of really like this idea of it's a little bit out of control."
