In a dystopic future, the humanity has been severely smitten by strange blind creatures that feast on living flesh, both human and animal. In spite of being blind, the creatures have a super hearing and can identify sounds from far away. The creatures are nearly indestructible and very effective killers, and once they hear you, you are most likely dead.
The movie follows a surviving family trying to keep alive in this harsh reality. The movie setup is incredibly well-built to transpire the precaution, the constant fear, and the direful consequences of an unthought action in this terrible future. The sound effects are awesome, and the director can successfully use the nearly-constant silence in contrast to the hassle of being followed by those creatures.
The acting is solid and helps to immerse the watcher in the well-built plot.
My only regret for this movie is that it ends during a climax, when we are not ready to stop watching it yet. It could be 30 minutes longer to explain some missing points and to show what happens after the ending.
Overall, an awesome movie, well-thought and beautifully produced in every aspect.
