Regular humans (for example, boxers) can KO someone with one punch, so I think it's quite believable that someone with preternatural senses, speed and timing could do so as well. DD's superpowers outstrip that of Batman (i.e., he isn't just a ripped rich guy...OK, he's not rich at all lol), so IMO not an apt comparison. The DD that I loved pre-Netflix could do all of the high altitude acrobatics that Spidey could save for stick to walls, he just didn't have the super strength. So while I also loved the Netflix version, I'm still happy they are making him a high wire act again. But if you prefer the more grounded approach, that's fine with me.His senses are superhuman, but his body isn't. He shouldn't ko'ing enemies in 1 punch, that's what I hate about this version the most, even The Batman got this right to an extent.
You have way more wiggle room for exaggeration with movements etc. on a page or in animation, look at some of the stuff that non Jedi characters do in Clone Wars or Rebels; it works because it's animated and the laws of physics aren't as strict within that medium. I just don't think it works for live action and tbh I don't really care about comics.
I just don't see myself ever enjoying this interpritation of Daredevil.
p.s. - I do hate the ketchup & mustard suit lol...
