Great acting, sure, cinematography, everything, and I enjoyed it. However, I'm surprised no one has noted the implausibility of the action . . . aside from surviving the grizzly attack without fatal infection, the dousing in freezing water in freezing temperatures would have put him to rest in a few minutes, not to mention when he got out & had all the wet furs and boots on him. Survival was simply impossible. Not improbable, impossible.
