From Netflix:

Against formidable odds — and an old-school diving instructor embittered by the U.S. Navy’s new, less prejudicial policies — Carl Brashear sets his sights on becoming the Navy’s first African-American master diver in this uplifting true story.

HBO recently showed this 14-year old film. As with most films about real-life heroes (military and other), the story is compelling while the film can be a bit corny, as in “wearing your emotions on your sleeve”. Nonetheless, Carl Brashear was brave, persistent, and an admirable role-model.

Spoiler: this old-fashioned film has a happy ending. Give the film a B and enjoy it.
