@kguillou I don't think that's true. I think you really have to look to find someone who says he's not even a contender. That's just a ridiculous stance.
For starters, he looks about a billion times better than any other cinematic Batman by a million miles. Not even going to post pictures of Batbale or Keaton Batman to make a visual side by side. We should all agree he has the best batsuit.
Dapper and playboy-esque Bruce Wayne who's appropriately gruff, driven, tormented and disturbed when the facade is removed. The cleft chin, the nose, the eyes, the stubble, the square Batman jaw. The facial features and expressions are basically a perfect fit for the character.
He's way more physically imposing and scary than the previous Batmen. His fight choreography... Do I even need to say anything? I don't think I do. A gif is worth a thousand words:
The cowl. The gadgets and machinery and how much variety there is between troop carrier jets, spider-like robot weapons and those magnetized devices he used to disarm Lex's thugs before the warehouse brawl. The physical prowess and feats. The way he looks when he swings with his grapple hook. The duality between Bruce and his alter ego. The torment Affleck portrays with his performance. The suggested rich history that colors and informs his actions and persona. His Alfred and how actively involved in crime-fighting he is. His cape and how much attention is devoted to making it move the right way, so much so that it's digitally added in post. The quotability of his lines. "Tell me, do you bleed?", "I'm real when it's useful", "Men are brave", "A beautiful lie", "I thought she was with you", "You were never a God, you were never even a man", "If there's a 1% chance", and so on.
His Batcave. His batmobile; a perfect blend of utilitarian, armored tank-like vehicle with a good dose of cinematic flare and sleekness. His Batman voice. Better than Keaton just talking normally and way
way better than Bale's... whatever that was.
Saying he's not the best is understandable I guess... I mean I don't get it but maybe you prefer Bruce to sport a turtleneck, smash things and talk about wanting to get nuts... But to say he's not even a contender? Puh-lease.
