The core idea of this film is great. Specially if your into history and like animals (dogs). That said, one is let down many times in the film. For example costumes definitely could have been more rustic. Its set in 20,000 yrs ago - perfect fitting, with inner wear. Come on!!! Also, a bit let down by missed opportunities in making some scenes more real - like in the end when he come back home. The people in his village were so cool around the wolf. At lease some shock towards the wolf would have been nice. This was set in a time where the wolf was a predator to them, but they were ok with him just lying there. In the mid, when the wolf and human are both in cave, the hero was dominant and submissive(like when he gave water) at the same time. I didnt get that. One more thing was 'you stink' scene, after which they take a bath(What!!!). Again for the time its set in - the smell is but a signature of any species, humans included. Why would one want to get rid of that? These are wild animals we are showing here. All in all - good movie. I wont watch it again though. But definitely enticed my imaginations.
