I loved the premise of this film, and was excited to view it with my 7 year-old, as the previews appealed to his sense of adventure and love of dogs. We were disappointed to find that it was subtitled throughout the entire film. Staying faithful to an aboriginal/"prehistoric" language was an unnecessary device,in my opinion, as we all have the understanding that our forebears did not speak modern English as we do. It detracted from an otherwise beautiful film, and was a barrier to a child with only early-reading skills as far as enjoying the film.
