I should structure the response by offering help in locating the movie or subtitles legally, suggest checking specific platforms, and if unsure, provide steps to verify the movie title. Also, mention the importance of supporting content creators by using legitimate services.
Also, if they're into subtitles, maybe they're watching for educational purposes or learning Indonesian. I can mention using subtitles as a learning tool, but again, through legal means.
To sum up, the response should guide them towards legal sources, confirm the movie title if uncertain, mention subtitle availability, and avoid providing any illegal methods.
