In first 5 minutes it was clear what it will be. The way of that hunting and pushing of animals to edge, then almost ridiculous behavior of main hero and his salto ...

European people 20000 years ago looked very like today Europeans - well, actors were with not much make-up or CGI, then acted very much like American Indians. I'm not expert in that area, but that seems just not proper. Then, how that 'alpha' man-wolf friendship was established was way too unrealistic. Especially annoying was talk about which turn is when :-) English subtitles were with too modern language. It should reflect old, limited vocabular and way of thinking much better. Spoken language was probably something fictional, what's best what can be done, so that was OK. But many details could be much more historically accurate, if they just took little care.

Reminded me about semi-documentary movie with same theme - first wolf who becomes mans friend, cohabitant, and then dog. Unfortunately can not remember title. Was far much better than this.
