He absolutely did, firing that tow cable into the car he plowed into just moments before to turn it into a vehicular morning-star to use against the other vehicles, and then using the gun on the front of his car to totally decimate that SUV with the mini gun, and then literally decapitating a guy with his front fender, and then blowing up those trucks with the Batplane, lighting KGBeast up with that machine gun, and you know what? It was beautiful. It was ugly, but, for the purposes of the story, I thought it was beautiful, because I see this as a redemption story for a Batman who's basically become so disillusioned by his experiences that he's forgotten his true purpose.
There's a line in "Under the Red Hood" where Jason asks Batman why he wouldn't just kill the Joker, and Batman talks about crossing that line would basically mean unleashing the monster inside and not being able to come back, and I feel like that's where this movie picks up. With Batman, after he's lost sight of that line. I know it pissed a bunch of people off, but I feel like it goes a great deal toward humanizing Batman. He's the king of deus ex machina; in the current comics, he's literally the God of Knowledge (I **** you not), and people always say that what makes Batman so great is that he's human, and that makes him relatable, except that he's really not. He's always portrayed as morally incorruptible and completely infallible, and, as we've heard, time and again, "to err is human."
I think that this story is as much about Batman's redemption as it is about Superman's, and it just works for me.
