I used to think there were two types of people: the ones who only use subtitles when necessary, and the unappreciative philistines who use them for no good reason. I was willing to die on this hill, arguing that they distracted from the purity of the audiovisual experience: the cinematographer's attention to detail, the glimpse of a tear in an actor's eye, the punchline of an expertly timed joke, and so on.
