even watching walking dead on the dvr i find myself scrolling back anyway. some subtle things that are on screen for a split second would catch my eye. for example the latest episode they mirrored daryl in one shot so his tattoo was on the wrong side. plus i rewatched the paintball mask guy trying to figure out who he is. so i naturally scroll back and forth whenever i have to, that just makes watching subtitles causing you to miss the scene not a burden on me.
