Interesting, suspensful movie. Good story, well executed. Having everything presented through the "screens we use everyday" was a somewhat interesting device, but also a bit gimmicky. There were several points at which it felt quite contrived and was a burden to the story rather than helping it. Nonetheless, it was a good story, well acted, with some nice twists. I'd say that it works inspite of the device rather than because of it.

Great film with lots of twists and turns. The format is innovative but may not work beyond this film. I would recommend!

A one-of-a-kind experience. A strong story told in a fascinating manner.

Interesting format,unique approach to story,however relationship between father and daughter is not explored enough.You dont get a feeling about them as individuals or their relationship
