So many twists and turns, it's like the filmmakers watched MEMENTO and dialed it up to 11. I hear that maybe I shouldn't have watched that version first from some, but what's done is done.

How dare anyone try to murder Kim Seol-hyun though? That I can't forgive!

Stunts - 80/100 | Surprisingly good stunts here, and quite a large number of them too.

Narrative - 70/100 | Terrific performance by lead actor Sol Kyung-gu, impressive from start to finish. Really that's one hell of a show he gave in this movie, by far the best part about it, in fact. The rest of the movie was a bit too convoluted for my tastes, especially the ending which introduces a few problems. Unreliable narrators can be a great tool but sometimes they're kind of annoying.

Fight Choreography - 70/100 | Not much typical choreography going on but the final fight is lengthy and brutal, somehow. Good action directing and stunt work, although this is far from an action movie so don't expect Hong Kong choreography here, it's just fighting for survival.

Enjoyment - 68/100 | There's grim and there's this. This movie is like an endless pit of despair. Goes a tad too long.

But South Korean thrillers are always a good choice because they frankly know how it's done.
