It's a borefest.
Except for the scenery. I couldn't watch in one sitting (HBO) - dozed off several times. Repetitious, tedious, too long. DiCaprio won the Best Grunter Oscar. He never had a scene that showed acting versatility, just a collection of 3-4 tortured faces. When he crawls into the moose or whatever to keep warm I was like Jeez even more bloody animal entrails? The characters of Fitzgerald and Bridger were much better acted. Bridger was my favorite character overall.
