As a work of cinema, Chasing Coral is ambitious and unprecedented. As a work of advocacy, it has the power to open eyes and make people at least try to save something that we frighteningly might have done too much damage to already. It’s also a film that isn’t afraid of making its advocacy into a personal crusade for the people involved, but it does so without being hokey, preachy, maudlin, or sentimental. It’s honest, unflinching, and unabashed in how it depicts coral as an unseen force that should unite us all. It’s also one of the most unmissable films of the year.
