Great film

This was done in such a unique way and it was so riveting. Everything was so creatively done and the whole concept was so intelligent. 99.5% of the time, a twist in a movie never surprises me but this twist was SO good.

A must see thriller for the suspense lover within us all. Manages to mix family with tear-jerking suspense. John puts on an amazing preformance.

the movie kept me interested throughout. the story was told in such an interesting and engaging way. i also loved John cho's performance. great job.
