In the animated series, Bruce is a really nice guy. That's how he should be IMO. Bruce Wayne is not Tony Stark
Absolutely agree, there is no need to make Bruce's civilian identity Tony Stark 2.0.
I personally have never been fond of the "billionaire playboy" aspect of Bruce's alter ego, both the Animated Series and the Keaton films never felt the need for it.
Instead Bruce was someone who used his civilian resources to help those in need, openly challenged political corruption, adopted troubled youths because he identified with their loss, supported his friends and while he was part of the upper elite scene he never came across as a overly-flashy trust-fund type.
To contrast Keaton and Bale:
Keaton - hosts a social event for a good cause, plays host but doesn't hoard and covet attention and keeps a somewhat low profile at his own party, plays himself a tad bumbling and eccentric but otherwise genial and kind-hearted, shows shades of his own personality.
Bale - arrives late to his own function via helicopter with 3 supermodels, stops the entire flow of the party so everyone is looking at him, gives a big speech that demonstrates an over-inflated ego and makes a point of demonstrating his wealth and power while acting obnoxious (yes I know its an act - its the persona that matters here).
Another contrast between them:
Keaton - invites VV to a meal, doesn't take her to the most expensive restaurant in town, instead opts to eat at his home, they attempt to eat in the formal dining room, Bruce makes fun of how over-the-top ostentatious it/and his house in general is and they instead eat in the much more homely and humble kitchen and trade personal stories.
Bale - arrives at 2 separate meals/social gatherings uninvited, with one or more supermodels, in flashy cars, to one of the most exclusive/expensive restaurants in town, behaves badly and expects the rules to be bent for him, then emphasises how his wealth makes him exceptional/exempt from the rules by buying/proclaiming his ownership of the restaurant itself.
These two couldn't be more different, and while one is more of an act than the other (Keaton's Bruce allows some of his natural personality to shine through, whereas Bale's is a complete performance) it makes it harder for me to like Bale's Bruce, because he acts like a jerk and his "Bruce" scenes are completely artificial.
Whereas I
like Keaton's Bruce because he seems like a real person I can root for/connect to/identify with, which again is something I think the Animated Series picks up and does well.
To put it simply, I think Bruce should come across as "old money" as opposed to "new money" in order to remain more likeable (And more separate from Tony Stark) and should show real aspects of his personality in his daytime persona, with friends and life-connections that aren't solely centered around his crime-fighting or some false playboy persona he's crafted in order to come across as a real and relatable human being with actual human connections rather than Batman's human skinsuit.
