The subtitles feature is a huge win for me. My partner is Spanish speaking so every film we watch requires a hunt through various subtitles sites(not being able to use srt files with likes the of iTunes is also a major issue when paying for films). Of course I know how to do it but it's one of those things that has really made we wish there was a good quality commercial offering(I'd be very happy to pay something like $70/month for a spotify type service).
