Subtitles can make you understand the conversations better and follow along closely. There are some movies that I find it hard to understand their accent and pronunciation, so subtitles make me follow along with moves well.
Depends on the movie. Sometimes I just turn on the subtitles because the area around me is loud, or I'm having a hard time hearing the dialog. Or if I can't understand them. But often I usually only use subtitles if I'm watching a foreign language film or something. I can't stand American voice overs, so any foreign movie I watch, has to be subtitled.
It depends on the kind of movie I want to watch . If they are foreign movies and they speak foreign languages like the Philippines movie that I've always loved to watch, I mostly follow the subtitles. They help me catch up with the details so that I would not miss any action. They help to improve the comprehension in a film and to also not cluster things together.
