There was NOTHING in this story that I could have predicted. It makes you question what the hell is going on from beginning to end and when things come to light, the truth just leaves you shocked.

Stellar acting by Kang Ha Neul and Kim Moo Yeol. Music did it's job creating the right atmosphere but nothing memorable.

I agree with what another reviewer said about rewatching being rather pointless since the mystery is what makes this movie - unless you're rewatching to look out for the details you might have missed the first time around, or to observe someone else's reactions/journey (that should be fun).

I'd also say that once you're lying in bed replaying the plot in your mind you might start noticing and questioning some plot points. But that didn't dampen my overall enjoyment of the movie.

Am really surprised I didn't hear about this movie before (found it in "more like this" from The Call and watched it because of MDL reviews and Ha Neul) - it truly deserves more attention.
