so you can gun shootouts in middle of popular European cities ?

I have never been to Europe but would imagine that "anything goes" overseas. So yes. Compared to America they have very little infrastructure ie cops or police force. Its very lawless. The wild west. Poor.

The whole film series is a sort of parallel universe. So sometimes you have to accept that it’s fiction

You just can’t compare Europe to America. I would never live there. The only reason JW4 is set there is cuz it’s cheap to shoot in that country. America is the elite. It’s not called EuroTrash for nothing.

This is world where everyone is a part time assassin, so it wouldn't phase them.

That's why those people in the club didn't stop dancing even after seeing John behead a man with an axe!

I didn't like the rip off, call back, or homage (take your pick) to "The Warriors" at all. Way too forced and cheesy for my taste.

Now, to answer your question . . . in a film where a blind man can dodge bullets, anticipate the enemies every fist and foot movement during the course of a fight, and shoot straight for his target (but during the break in action has to wave a stick around in order to avoid bumping into something) . . .

In a film where hundreds of bullets always miss the key players but in which the hero (rarely) misses . . .

In a film where each enemy fighter patiently awaits their turn to fight Wick instead of piling on at the same time . . .

. . sure, why not?

You do realize this is set in a fictional universe where police aren’t really a thing? Either you’re trolling or just stupid

You can in the movies lol, if you want "realism" go watch a documentary.

It was completely ridiculous, yes. Especially the dance club scenes. Guns firing, people getting shot in the face, no problem.

And honestly that brings me to one of my continuous gripes with this franchise: the gun violence is toned down (censored?) so much that it is practically PG-13. All these constant headshots should have skulls blown open, faces exploding, eyes, blood, and brains blown all over the place, arms and legs blown off, to the point where it would be seriously disgusting to watch. But it's not, and it gets strangely boring.
