I’m reading your question as a comparison between the film Obsession and the Indian film Sadma. They are different in genre, tone, and storytelling: Obsession is a modern psychological horror/thriller, while Sadma is a classic emotional drama centered on memory loss and care.

Main difference

  • Obsession leans into fear, suspense, and unsettling tension, with the story built to disturb and surprise the viewer.
  • Sadma focuses on tenderness, loss, and human connection, with the emotional core coming from the relationship between the characters played by Kamal Haasan and Sridevi.

Story style

  • Obsession is designed like a genre film, so the audience expects twists, danger, and psychological pressure.
  • Sadma is more of a tragic romantic drama, where the emotional weight matters more than shock or horror.

Why people compare them

  • They may get compared because both deal with intense emotional states and vulnerability, but they are not the same kind of movie.
  • If someone says “Indian film sadma,” they may just mean the film Sadma , not a category of films.

Simple takeaway

Obsession is about dread and suspense; Sadma is about heartbreak and memory. So the biggest difference is not just the country of origin, but the entire emotional purpose of the film.
