Watched on opening night.

The only things I can fault in this film are some dodgy special fx choices, the largely irrelevant detail of the outdoors on the mountain being quite clearly fake (which, yes, it needed to be for safety reasons). And, wildly inappropriate layers for that kind of climb (a very small part of the film). If you can get past that, you’re good to go.

However overall this is a decent film. I’d say it feels more like horror/thriller instead of just thriller. The story unfolded in a way that made it overall more intriguing as you learn more and more about the characters. I enjoyed the direction it went in.

If you like the premise, go for it?

Notes: The ending is not the same as in the manga. The film is also bilingual (70% Japanese, 30% Korean).

Warnings: Gore.
