I thought it was pretty good, brutal and realistic. As far as home invasion movies though, The Strangers creeped me out a bit more and had better atmosphere imo. And Funny Games was far more brutal I think. I give Kidnapped 7/10
Kidnapped tops Funny Games and The Strangers. Thought Kidnapped was great, and very original.
Funny Games was good.
Hated The Strangers when I first saw it, but have come to appreciate it more. For me it is the epitome of - Stupid things people do in horror movies. Give me a shotgun against unarmed killers...I like my odds.
