What a bad movie. Does someone care about the father and son relationship in this movie? About Leo's motivation? It's essential, but it seems like an afterthought in the movie.
Should we laugh at him because what happens to him is absolutely hilarious—the worst and the worst and the worst again because God is obviously punishing— or suffer with him, feel the pain of the journey, even if he seems to be able to endure everything? A meaningless journey. This isn't Gravity. Bullock fought against her fear and her unwillingness to live. Dicaprio is a robot. He shuts up and do the thing. The thing being different things.
They're walking from there to there. We don't really know why at the beginning. Then it goes on and on. It's not just Leo, it's also the others guys because, apparently, we don't have enough and they aren't empty shells. The bad guy is obviously bad since the beginning. He's almost shouting: "I HAVE BAD INTENTIONS AND THAT'S WHY I AM BAD". Whatever: leave him alone with the main character.
And I've rarely been less impressed by what is supposed to be an impressive prestation: DiCaprio does almost nothing, he's just there and, indeed, has saliva. If you've played to a video game ecently you won't be surprised by the immersive filmaking but you'll never get the control. You'll never play. You'll watch someone ramping, yelling, a gorgeous shot of nature, other characters walking somewhere while being cold and nervous, etc...
After two hours you just want him to kill him already.
Please. Kill him.
This movie is a waste of actors, cinematographer and subject.
PS: I loved the big wave of CGI when the bear appeared.
