I really don’t get it. I realize this is likely a me thing. I’ve never read any his comics. He doesn’t have any powers. He just shoots people. I think he shoots only bad guys, right? Seeing people get what they deserve is nice but you could also do that with a robot mech suit or giant green imaginary weapons or laser beams from your eyes. I could go on. He wears all black, so he’s emo, and shoots people. I just don’t get it.
Batman’s endless arsenal of gadgets may not technically be a superpower, but he’s typically written in such a way that they are treated as one. He’s not really any different from most superhero comics, not in the way that Punisher is.
Imo John Wick is definitely on the same levels as batman there. Dude has some reality-bending gadgets too and beyond human levels of training/endurance.
