Poor selection, poorly executed. There are many better images and imagery to use, and yet the author's choice doesn't give you a glimpse into really great, compelling images, but rather tries to give a snapshot into a variety of select causes. The art should have come first, not the issues.
So you're treated to a variety of causes, moments, issues which reads chronological whereas it would have been much better to receive just all the really great dissent images with more commentary and context.
