This movie suffers from not really knowing what it wants to be about. I could never tell if it was about family/tribe dynamics, the first domesticated dog, or or the struggles of being a teenager 20,000 years ago. And as a result you have a movie that doesn't feel like it ever gets going. I read that this was completed last year and initially supposed to be released Summer 2017. I'd imagine it wasn't because at the end of filming they really struggled to figure it how to make it work. The boy's relationship with the dog was the only worthwhile part. But I'm truth I never really cared what was going to happen to him.
