10/10 for acting, cinematography, and plot development

1/10 for the second half

This had the potential to resolve itself epically but instead quickly descended into a messy free fall of nonsense.

There are so many intensely gripping Korean films I was sure this would be one of them. And for the first half I was engrossed. But the second half was a huge let down.

The acting and production quality are fantastic but the resolution sucks. No spoilers.

Watch the original Old Boy again, or The Chaser instead. This film has nothing but disappointment at the end.

Boring.
