Here is an intro,
Naturally enough if you are interested in this movie it is because of the action. It does not disappoint. It almost never stops. It has innovations; new locales, new weapons, new scenarios. This is all good. It also introduces the “double tap”, where the good guys shoot the bad guys multiple time to make sure that they are dead.
There is the normal chicks who have awesome fighting skillz gag. At least they look good doing it. Of course, the fight scenes are ludicrous, where the combatants would be hamburger after 20 seconds. But we need to have a flick worth watching, so we will ignore that. And of course, the bad guys come at John Wick one (or one and half) at a time, defeating them in detail. Fortunately they are mostly stupid, showing their full body so that they can be shot more easily.
When we last left John Wick, he had a huge contract on his head. Everybody was gunning for him. Lots of action ensues. The tension never really stops. Without revealing too much, he does survive the movie, though just barely. There is also a twist at the end, seemingly leading to another installment.
If you are looking for what some might say artistic fight scenes, then this movie is for you. Even if you just like fight scenes, it is for you.
