I feel like this too with using subtitles. My eyes will be going through it until the movie or TV show is over. It's a focus holder whenever I'm watching any movie or TV show.I have mixed feelings. My eyes are definitely drawn to the subtitles more than I would like, but I don’t need to constantly play with the volume between dialogue and gunfire/explosions.
I admit I use the subtitles more frequently for shows where most characters have non-american accents.
