It’s funny, isn’t it?
I heard that even the native speakers of English, they also have a trouble with understanding what the batman is saying. Without a subtitle, I would have enjoyed the scenes of actions only. I know someone, who didn’t understand any words said in the movie ‘Batman Dark Knight’. He went to the cinema when he was at UCLA. He said on his blog that he blamed himself, his lack of English ability. However, he regained the courage after watching this video. It was not his fault after all.
