Query: Amazon Unbox is an awful venue.

Movie is fine. We wanted to download to watch at leisure. The downloading glitched part way through. Had to stream it 'live' from Unbox. Not what we wanted to do. And, Unbox charged me TWICE for the movie: once for the glitched download attempt and once for the 'live' stream. Ridiculous! Won't be using Unbox again.
