Wow this movie sucks

So there's this guy with his son and he wants to stay undetected so he makes a big fire every night.
And he wants to get to the sea so he walks a lot instead of building a raft.
And he's hungry and seriously starved out so he leaves the food shelter behind asap.

And it's quite unclear how damaged earth is. There are dead trees and falling cgi trees but there are obviously still smaller plants standing around. The plot is pretty much non-existent, I guess they were heading just to make it immersive instead. But that also didn't work well, despite the permanent use of a grey filter. There's like a tiny very lowkey conflict going on between the suspicious hardened father and the want-to-trust-people son, but it never affects the story at all.

And basically that's it.
And no I dont believe that any catastrophe, at least none that could have happened in this movie, would kill literally all plants and animals so..
