This article encapsulates everything I feel about the subject. I hate using subtitles, but sometimes I just have to in order to hear what people are saying due to streaming services messing with the actual sound mix using their stupid algorithms. As for reasons I hate subtitles: they distract from the actual film and can occasionally spoil things happening. If subtitles are on the screen, my brain forces my eyes down to read them, and I inevitably lose out on some of the nuances of the visual part of the visual media.
Additionally, if I'm watching foreign films, I get this urge to learn the language so I can stop using subtitles. Maybe I'm a curmudgeon, but I just can't stand them. I can't imagine watching Redline for instance with subtitles on. Yuck.
