This is fantastic.  But is it a trailer or a self-contained film?  If it's intended to be the latter, I would recommend a re-cut.  Slow it down, especially the scenes with the barages of textual information.  Elaborate as much as possible.  I understand that sometimes the message needs to be short, but this feels like an over-stuffed trailer or 30 minute documentary condensed into a hurried 7 minutes.  Just suggestions.  Thanks for this valuable and powerful piece.
