Subtitles kind of ruin the viewing experience for me. The whole time, my eyes are being pulled down to the bottom, away from the actors' faces, away from what's happening on screen. I'm basically reading a show instead of watching it specially anime/kdrama/documentary/movies that I want to keep the audio in original language.
I got frustrated enough that I built a Chrome extension to fix it. FloatSub lets you move your subtitles into a floating bubble and place them wherever you want; center of the screen, just below a character's face, wherever your eyes already are.
