Yeah no. I think you’re confused because Batman Begins came out in 2005 which was decades ago.
If you forgot he’s actually also known as Bruce Wayne and he knows how to smile and have a good time. Any actually cared about the various villains that he fought against. He used to be a clever detective.
Post Nolan he is has lost a lot of complexity. That complexity of the character offset his serious side when the cowl came on.
Look me dead in the eye and tell me Nolan’s Batman is better than BTAS. Or is even in the same ballpark.
