How many assassins does a man have to kill before the rest take the hint?

20 million bounty makes a guy do anything.

Agreed. There is no way that many low-level assassins are that dumb. Especially when they see each other dying so quickly, constantly, and pointlessly right next to them. They would immediately turn and run, hide, regroup, etc. like anyone that doesn't want to die. Which is, basically, everyone. No one wants to be cannon fodder. WW2 sucked.

Realistically, the only ones brave enough and smart enough to take him on would be the elite killers, which would be very few. They would most likely be trying to outsmart him, not this dumb-ass kamikaze run-straight-at-him with a fucking hatchet nonsense. I'm not sure if the producers are trying to insert comedy or not, but sometimes it is comical.

Or do it the right way: set up an automated sniper-rifle face-recognition scanning system in a web that covers the entire city/area via flying drones and/or ground-elevated-placements. Just wait for one to tag him and get an instant headshot. Duh.

They can still go after him but I would have gone in a low risk way, like sniper rifle from a distance.

In Europe, overseas, people have very little -or nothing to live for. The poverty there is insane. Terrorists , ISIS, the axes of evil. The place is lawless after we pulled our troops out. America gave them hope, gaven them freedom. We gave them a life. Im sure those assassins put food on the table going after Wick. Its a job. If they fail their families will get a few bucks. Just $5 goes a long way in Europe. They can live off that for weeks.

The whole series after the first one went way too far over the top IMHO, and not just for this reason, though it's a good one. As I've said before, they forgot the criminal underworld in this movie was an underworld. You got the real sense that it had reached a modus vivendi with mainstream society, and as long as the thugs were only fighting and killing each other, the regular authorities would leave them alone. The cop who shows up at Wick's door after the first big fight knows exactly who and what Wick is, but since John hasn't killed anyone but other thugs, he goes about his business (the cop also wants to live).

But from 2 onward, it just went too far. Now everyone is in the underworld. And when John Wick is declared "excommunicado," literally everyone on the street stops to listen to the message, and then half of them start chasing him. How are there this many professional assassins in society? What work is there for that many?

Movies and TV shows do this as an excuse to have cool, wonderfully choreographed fight scenes, but honestly the impossibility of it just goes too far for my suspension of disbelief and it takes me right out of the story. In the Netflix Luke Cage show, when Cage is rampaging through a building full of gangbangers, literally tearing through the walls, and bullets are bouncing off him, not one of the thugs flees from what is essentially the Terminator in their midst. They all charge aggressively toward him with their observably useless handguns, wearing an "Ima fuck you up" look on their faces.

Please.

Or in "The Raid: Redemption" no one ever gets tired, though they're exerting themselves at sprint level effot for long, long periods, they take crippling damage that would hospitalize any real human being, and it maybe knocks them out for a few seconds, after which they get up and fight like nothing at all has happened. It's just too much.

It's silly. Wick is notorious across the globe as the deadliest assassin that ever lived that literally heaps up hundreds of bodies at a time of trained killers. You're better off going to the 7/11 and buying a lottery ticket than hoping you can squeeze in a lucky bullet. I really wanted just one scene of some bearded biker guy being like, "F that, those guys are idiots" and popping a beer to watch some tv. Just for some grounding context of what's happening.

They only had 15 minutes of story in this film at most. What else was going to fill the next 2 hours and 45 minutes?

A smarter group of people would have totally ended it with ignoring the action route and turning it into a mystery thriller. John Wick would have been investigating the world itself, how it was formed and how it worked. But nope, he just took it all at face value.

This is about as thoughtful and clever as pointing out how suicidal the enemy NPCs are in Ninja Gaiden.
