Keaton has proven himself to be as adept at action seriousness as antic comedy. In Knox, his hand is steady...

This is Keaton’s film to carry every step of the way, and he turns in a typically fine and layered performance as a man who might find relief in the loss of his memories, given all the dark acts he’s committed.

It really all depends on Keaton giving a serviceable performance to salvage whatever is left, but even he falls short.

There’s an aimless quality to the story’s flow that turns a lot of Knox Goes Away into a bit of an indiscernible blur ... Still, that ending absolutely elevates it to a point where I can say I’m glad I saw the film.
