How do you evaluate the movie "The Revenant" directed by I?árritu?

This film combines a low-angle ultra-wide-angle picture with a large depth of field. It was shot in Alberta, Canada and southern Argentina, showing magnificent forests and vast snowfield scenery, which is extremely shocking, such as Lubezki said: "It's like you're looking through a window at everything." The ultra-wide-angle lens will show a special perspective, and the edges on both sides of the picture will be distorted. However, in natural scenery shooting, such as the forest at 00:40:25, all the trees seem to grow toward the middle. This is different from the human eye. The visual viewing creates a strong visual impact. At the same time, the ultra-wide-angle lens's difficult sports photography always uses a "wild animal-style" spectator perspective instead of the character's point-of-view lens, and combined with a variety of fixed-focus lenses, people and animals become part of nature, completely Integrated into the natural scenery, the magnificent and lifelike pictures give viewers a strong sense of immersion. The film also uses a large number of ultra-wide-angle lenses to shoot medium shots, close shots, and even close-ups of characters. This technique is relatively rare, because except for the close-up objects that are clear, the background becomes completely blurred and blurry. At 00:25:08, the mother bear tramples Glass under her feet. The camera shoots upward and slowly moves up to close-up Glass and the mother bear, reflecting Glass's powerlessness and the mother bear's overwhelming strength and ferocity; 00:34 At 01:54:48, after Glass climbed out of the horse's belly, he used a 14mm wide-angle lens and a lens to achieve a close-up. This causes the distortion on both sides to greatly increase, forming a distorted picture. Similar pictures appear twice in the film, both of which fully express Glass's psychological emotions.
