Cast Away Movie Critique

Cast Away was a very interesting survival experience. Put a man that runs his life by time and lives a controlled and planned life to the second and put him on a remote, lifeless island which causes him to live his life completely opposite from the way he would if he were home. It was man vs. nature as Chuck Noland (played by Tom Hanks) on an island alone for the majority of the movie.
Chuck Noland is a Fed-Ex systems engineer. The night after proposing to his girlfriend Kelly (played by Helen Hunt), he gets on a plane that is carrying a cargo that he is escorting. How ironic is it that he told Kelly that he would be right back and then ends up taking an extreme nosedive in the ocean. Luckily, Noland washes up on the shore of a remote island. For the next four years of his life, he is on the island alone with his only friend being a bloody volleyball he names “Wilson”. Then one day, a wall of a portapotty washes up on shore, and he is able to use it to make some sort of raft to hopefully get him home or at least far enough to be noticed and venture the roaring sea once again. After much physical stress and the loss of his best friend Wilson, he is saved by a passing boat, and is returned home as somewhat of a hero and viewed as the pinnacle of strength and survival. Only thing is that the only thing that pushed him to survive for four years is now married with children putting both Kelly and Chuck in a very awkward position.
Chuck Noland kept his sanity with his repeated conversations with “Wilson, the bloody volleyball”.

I understand four years is a lot of time to cover but a little explanation of key moments would’ve done the movie better. Maybe, they should’ve showed the development of
