The Batman: 10 Things Fans Demand
2. Bruce Wayne
One of the things that made the Batman Telltale series so engaging was the focus on the duality of Bruce Wayne and Batman, and how they impacted on each other.
Comic book films tend to lean very much into the superhero persona of the protagonist rather than their civilian identities, after the origin movie, so a well-implemented version of the Bruce/Bat combo could really add some much-needed variety to the genre and help to cement Reeves' Batman as one of the deeper versions of the character.
Even the comics haven’t explored this idea to a great extent, usually treating Bruce Wayne and Batman as one and the same, which works for a version of the character with decades worth of history, but not so much for a new standalone movie. If done right, the fans will remember it.
