Revenant Things bugged me in Gravity. Similar things bugged me in Revenant.
While a true story, they were oblivious to the effect of hypothermia and cold water exposure in the winter. And that old story of climbing inside the carcass of a large mammal to get warm has been proven false many times. The animal gets cold about as quick as a steak taken off the grill in cold weather. Hunters know that they cool off pretty quick. Certainly would not retain heat all night long. Could provide shelter though. OK, I guess. It appeared to have been lots of work to make. Leo did a good job.
