I feel you, but at the same time it's Batman. Even in his comics they do grounded stories about him. I'm fine with a realistic, grounded, dark, and gritty Batman. It becomes a problem for me when they try doing that shyt with Superman.
My biggest beef with the Nolan Batman films is Bales Batman voice, that shyt was terrible and at times distracting. BvS is a bad movie, but they got a LOT of things right with Affleck's Batman. Using the voice changer was smart, as it allowed him to be intimidating, hide his voice, but not sound like a fukking moron that half the audience laughs at.
As far as action goes, the fight scenes are mostly passable, though the whole sequence in China is just fukking dope. The car chase in TDK might be one of the most iconic car chases ever filmed.
