But one woman wasn't so impressed.
Allena Hansen was actually mauled by a bear, on her ranch and suffered horrific injuries.
“I'm sorry, when I saw this I laughed all the way through it. I really did. All I could think of was 'acting' and 'this is silly. That's just goofy,'” she told IE.
She described the attack, and said: “It grabbed me by the ears, bit my face and took me down. The next I knew was lying in the fetal position in the creek bed with this 200-pound monster sitting on my shoulders and biting into my head trying to tear my face off. I could hear the bones crunching. I could hear my sinews ripping.”
Her dogs came to her rescue and fought off the black bear.
It took years of cosmetic surgeries to rebuild her face and mouth; she has made amazing progress.
“It ripped my nose off. I have pretty extensive scarring… It tore out my upper palette because it bit into my face. It tore out most of my bottom teeth and my top four [teeth], and ripped my ears off,” she said.
The bear that attacked her was much smaller than the huge one in The Revenant.
She said DiCaprio’s only chance against a bear would be to play dead and he would never be able to take out a bear this size with a knife.
“I can't imagine that three stabs with a knife in the shoulder blade are going to make it through the rib cage into the heart but it's a tall tale, and beautifully told,” she said.
