'John Wick: Chapter 4' wonders, 'When does this all end?'

In previous John Wick films, Keanu Reeves played a retired hitman out of revenge. In the latest entry, John Wick: Chapter 4, his reasons are a little more simple — he just wants to be left alone. Wick's quest for freedom takes him all across the world, as encounters would-be assassins, busy traffic, and a sadistic French aristocrat.
