Regarding "exclusive in isaimini," I couldn't find any information on Isaimini being an official platform for downloading movies. If you're looking for a specific movie on Isaimini, I recommend verifying its legitimacy and safety before proceeding.
Type the movie title, "Thanneer Mathan Dinangal," in the search bar and check if it's available on the platform.
If you're satisfied with the terms, click on the download or stream button to access the movie.
