The central character is lovely, and immediately seems very watchful. Hints about his past have been presented, and it’s anticipated that further details will clarify what's causing these reactions in our canine protagonist. Something unusual is happening, but the human character appears either deliberately overlooking or simply unaware of typical dog behavior and abilities. I really enjoyed the animal star of this movie; I would like to see him in other films because he has a remarkable screen presence.
