To You Sweetheart Aloha explores four themes:
* Productive Aging: Leaders in gerontology call Bill’s experience “productive aging”, an aging process where at 20, 50, or 95 one is socially engaged, is exercising body and brain to ensure high physical and mental function, and is expressing oneself creatively.
* Intergenerational Relationships: explore the sincere, unvarnished, and compelling dynamic between two people bound by culture, music, and a genuine affection for each other—in spite of their almost 70-year difference in age.
* Caretaking: the film exposes conflicts that can fester amongst caretakers and the elderly when there is growing loss of independence. It explores various caretaking roles while revealing misunderstandings that arise out of simple naïveté or self-preservation.
* Art and Aging: a musician is liberated from his personal loss by returning to performing and singing the music he loves. By using his art to entertain adoring audiences and to connect to a new generation, he experiences the joy and pain of life and revives himself in mind and body.
