The movie Santosh Subramaniam deals with several themes, including:
The story revolves around Santhosh (played by ), a perpetually happy-go-lucky young man who believes in living life on his own terms. His philosophy is simple: avoid tension, enjoy the present, and never take things too seriously. This attitude is a constant source of friction with his overbearing, disciplined, and practical father, Subramaniam (played by Prakash Raj ), who wants his son to be a responsible and ambitious businessman.
The rest of the film follows Santhosh’s journey as he cleverly, and with a smile, bridges the gap between his ideology and his father’s expectations, ultimately delivering a heartwarming message about family and self-acceptance.
