Agreed. That is the Batman we need to see on film!
I absolutely love this exchange from JUSTICE LEAGUE: DOOM...
Oh, how I miss Dwayne McDuffie.
I've been saying it since the topic of a JL movie came up. Batman should be older.
1.) He would be established enough that this sort of tech is viable enough. He's studied this stuff for years, and he's able to apply it to these sorts of situations. Be honest, could a green Batman in his first year on the job locate each metahuman and uncover their secrets and weaknesses? He's the world's greatest detective, but, that requires him to be an established character who's been around for a while. You don't just start out at that level, you have to work your way up to it.
2.) The Batman is an urban legend. With the exception of Gordon and a few cops, Alfred, those he's rescued, and the criminals, no one should definitively know that Batman exists. They have their suspicions, and the people of Gotham should see the Batsignal, but it still should be hearsay, and they should still question whether or not he's a hoax.
To be frank, Batman should be the Jersey Devil. He's barely recognized outside of his region, and, if he is recognized, it's on some tabloid rag a la the Weekly World News, instead of the Daily Planet or the Gotham Gazette.
3.) He should change his approach later on. Not right away, but later on. He remains a myth long enough to gather all of the intel on the Justice League, and then, as a strategic move, he makes himself known. He earns their trust, he builds the team, and, all the while, he's making sure that he knows exactly where to apply pressure if ever the need should arise.
4.) Why the distrust? Batman should be sympathetic. We should think he's an *******, but, when he starts listing reasons, we, as the audience, should say "Oh, that makes sense." On that note, I actually think that Man of Steel did a great, albeit, unintentional (or was it) job of setting the stage for this. From the wanton destruction and lack of concern for human life to the way Superman straight up executed Zod, that's reason enough for Batman to be paranoid. Factor in that he's, maybe, 3 or 4 years past his prime, and he realizes that he needs to have things in place in the event that he's not there anymore.
5.) I just want a reason for Jon Hamm to play Batman.
If they did a Tower of Babel/Doom thing, though, I don't think they should go right into it. Keep it as an underlying arc. The audience sees Batman building his plan in the first film, but it doesn't come back to bite him in the *** until later.
