Also, maybe the user is concerned about costs. If they can't afford legal services, I can acknowledge that but stress the importance of respecting copyright laws. Perhaps suggest waiting until the movie becomes public domain or when it's offered on free platforms.
Another angle is the quality of the download. Torrent sites might not offer the same HD quality as legal services, which could affect the viewing experience. I can mention that legal platforms often provide better streaming options.
Also, check if the movie is available on YouTube Premium or other platforms. I think Nallavanukku Nallavan was released in 2019, so maybe it's in the public domain in some regions? Probably not, so better to stick with legal streaming.
I remember that Kuttymovies is a torrent site, and distributing copyrighted content like this can be illegal in many places. So the first thing that comes to mind is the legal implications. I should warn the user about the potential legal issues and encourage them to use legal streaming services instead.
