It's good thriller. The bad is storyline .whole movie doesn't explain why vallain kill people. Police was so incompetent. I cant stop saying why they so stupiddddd!. A guy found murderer but decide to let him to kill her cause want to save his sister, end up it's just a lie. Plot very cliche.. vallain have many chances to kill her, and decide to having conversations before kill and then she get away again n again. I almost stop in the middle of movie bcs the whole plot seems so stupid to make it look scarier.
