This is about ignorance for bad people around us. If we ignore them, they may damage us. It's police task to do it, but everybody should be more or less be responsible for what happens around him, at least where they live. Lesson is that it is dangerous to live ignorant life and ignore even small warnings we may notice in neighborhood. Movie is filled with fear, worry, hope, expectation, excitement, mystery, seek and hide. There is positive ending that brings us feeling of salvation and freedom. Had this movie just a bit more details, it could be worth 10 stars.
