Only worth watching cuz its 90 minutes long. IMHO it could have been shorter. There is really on thing that makes film ok - ish and thats the cinematography. Literally everything else is mediocre.. poor to some extent.
Honestly this film is definitely fiction if antthing cuz I mean, that last scene when Alpha fights the big cat.. just c'mon director dude I get it that you are a dog guy but thats just way to unrealistic. Had it been a fire breathing dragon it would have made more sense. And I don't know what sort of training Keda has received from his tribe but judging that he was strong enough to break through 3 inch ice with a flimsy stone knife (not to mention he held his breath for a good 2 minutes under a freezing lake without drowning) he may as well join the Avengers, he ain't no ordinary caveman. Surely his ancestors listens to his prayers and grant him with superhuman strength or something. You tell me, I don't know.
I also feel bad for the other actors whos sole purpose was to convince viewes that this film is in fact.. well.. based on cavemen who lived 20k years ago. To me it was not plausible.
