I love this film because it doesn't try to make the regular drama -"everybody died" or"everybody happy" it shows something else. The bottom line of this film wasn't to save the crew from the submarine but to put the soul to the next level and if there is one person that you can save you have to save him.Maybe most of the people who saw the film ,saving this strange person- Makovetskiy(Chernenko) wasn't necessary for them but it was.Like Makovetskiy's character says in the film :"The world payed so little attention to me that I thought myself dead"and maybe because of this he was worth saving.By saving Chernenko they save their souls. Very good actors the best music by Ennio Morricone
