Not sure why this franchise gets so much hype.
This particular installment has nothing that makes me go: wow, great action movie.
That's not because there's no action in it. Quite the opposite, yet the action is just dumb.

The dialogues are stupid. There's basically no story whatsoever, no plot other than "John Wick survives the most absurd stuff".
It's very often quite absurd without being selfaware - with a few exceptions, like the opening knife fight. That was entertaining in its hilarious absurdity. That was the only thing entertaining, though.
Fight choreographies are ridicolous overall. You can see the "enemy" actors holding their position, arms, legs, ect. for Keanu to do his part instead of reacting to the actual fight. Most of the time they are simply way too passive.
Maybe that's more of an issue with the cut, though.
Weapons are conveniently unlimited ammo when (film)shots need it, while in other situations Wick loads for example a shotgun with two round but can fire like 5-7 times. Overly brutal killings of enemies with headshots when they are already down. Usually with surprisingly atrocius CGI gunfire. The opening knife fight? CGI and gummy knives everywhere.
This movie is just more of the same without any merits. It goes the same direction as the Underworld franchise.
Just that this movie is quite nonsenical all around in addition. And for what? A fourth installment, of course!
The only good thing for the 4th movie is Wick working with King to bring down this assassin's guild as it seems. That seems to be at least some plot to be had in the future.
