Yes, much more interesting. Bale did that for two films. Never matched Keaton' awkward first meeting with Vicky Vale. Or him wilding out against Joker in Vale's apartment. Or him trying to explain to Vale who he really is. I think it's because the flamboyant persona is so obviously fake. So there's a palpable distance. And the pained persona hidden underneath usually translates to him brooding. Bale is good at brooding, don't get me wrong. But it's fairly one note. Keaton genuinely stumbling through society, not quite knowing how to navigate through BS high society talk is much more humanizing.
