For me, the video represents an obvious example of the Society shamelessly promoting itself rather than its message. As others have noted, the production costs for this will have been considerable, and all paid for out of funds dedicated for the worldwide work.
Publishers would have every right to ask what this video has to do with spreading the good news of God's kingdom at a time of unprecedented urgency in the final stages before Armageddon... but I doubt they will.
