This movie replicated most of the plot points of the original but with none of the execution. None of the characters were that interesting so the pay-off wasn't that effective. Josh Brolin constantly changes personalities in order to fit into whatever the plot requires him to do. The camerawork was uninspired. The third act was basically just two people delivering exposition. Sharlto Copley was the one highlight, even though he wasn't amazing, everyone else was just ok.

This Movie is pretty good and you may want to switch off half way through but I bet you won't be able too.Although the endings twists and turns into what you'll least expect and quite frankly not for the easily shocked.This film overall is well worth a watch and is worth far more than the rating it has.Recommend a watch.

Became violent revenge porn. Didn't finish watching. Until 45 min mark I thought it was going to be an interesting psychological study of isolation and coping with confinement.

this is a good movie, make u curious until the end. if u never watch the Korea version i suggest u to watch this version first, i think the western version better than the Korea version. it is thrilling and surprising... this is one of josh brolin best movie u must watch!! ignore all the critics, if u like thriller and mystery genre movie then u will like this movie.
