This was an entertaining film although a little on the slow side. Overall enjoyable ride which plateaued a little in the middle. The one massive issue I had was that when our two protagonists looked tired, cold and hungry, the dog seemed to be full of energy for the entire film.constantly bounding about like he was on a morning walk in the snow.....the little guys feet would have been so frost bitten and they should have at least made comments towards his condition as every time I saw him leaping through the snow it just ruined the tension. Ok for a Sunday night view.
