I wasn't as hot on John Wick 3 as you, i wasn't happy with some of the editing choices and i thought many of the fights actually lacked some of the impact the previous ones had.
There still no substitute for throwing a bunch of underpaid stunt peeps off windows, through glass, into concrete, like good old Hong Kong (and more generally Asian and SEA cinema) did, but they're still a beacon of excellence, for sure.
But like, John Wick 3 wasn't all that better than some of its recent clones, like Atomic Blonde or even stuff like Villainess, which themselves were pretty good but not great.
I think modern Mission Impossible movies are the apex of Western action cinema, at the moment.
I'll say though, with the focus on guns, JW cuts itself a more peculiar niche than The Raid movies did (another action world wide hit, that blew up massively for whatever reason).
