Yes, it was slow. We,too, were ready to scrap it. We thought it would be another "found video" crap.
It was good, yes, there are subtitles but sooo little dialogue which was fine.
Be patient, the music is great, the scenery too. This no Avatar or Transformers nonsense....this is a thinking movie.
Found it on HOOPLA, which is associated with most North American libraries, Free!
