Your video needs to hit somebody between the eyes and make the viewer feel something. That ‘something’ could be happiness, sadness, fear or anger. Any of those emotional reactions will pique the viewer’s interest. In any case, whatever emotion comes to the fore, you need to ‘lay it on in spades’. There really is no point underplaying this. Clearly, you don’t want your video to get lost among the millions of others exactly the same.
