I have it on authority...
...from those I know who are police/military (not counting Air Force tech heads) they are trained to shoot for center of mass.
This particular trailer also does little for me. Then again, while I enjoy the superheroic genre, it works better in animation. Pretty much any time I see a live-action Superhero film it just makes me want to watch something animated when I get home.
Side note - we saw Spider-Man: No Way Home this week (Spidey is the best), and it was good. A solid film that served as a love letter to the last 20 years of films, and a reboot of itself, but... It suffers from coming out two years after "Into the Spider-Verse," which covered the same Multiverse theme, and did it BETTER. No Way Home was good, but Spider-Verse was next level.
One small Batman detail that's been lost in the last 20 years - a line from Frank Miller's "The Dark Knight Returns," (with the quick explanation that this Batman wears the black bat in the yellow oval version of the logo) is the simple line, ".45 caliber. Has to be. The plate holds...why do you think I wear a target on my chest? Can't armor my head." Current black-on-black blows that.
Not a particular fan of the casting choice. The writer/director has done several other films I enjoy. To me the thought of Batman forming the gun that killed the Waynes into the bat logo on the chest is pretty dumb, but it's a pull from a Grant Morrison comic.
I dunno. I basically find it difficult to judge by trailers. Trailer editing got terrible and formulaic around 2005.
The "seeing a live action Superhero film makes me want to go home and watch something animated," thing above? I suspect if I see this film it'll just make me want to watch "Batman: Mask of the Phantasm," again. Boy, if you want to watch a truly excellent Batman film, it's easily the best Batman film ever made. If you've never seen it, you've missed out...but it's on HBO MAX with a subscription, or a ton of other services as a rental.
