Choreography, that’s what it all comes down to. Choreography. At least when we are dealing with action films that don’t have much to offer in the way of storylines.
The first “John Wick” film had a semblance of a storyline. The killing—nay—the cold-blooded murder of the puppy of the titular character (Keanu Reeves) by a ruthless thug is what initially triggered (pun intended) the hero. That act alone compelled him to carve a bloody swath through the many minions of an organization of assassins called the High Table.
