Fin

For all its sobering reporting and imagery, Fin also has moments of pure beauty, as when Roth literally swims among sharks, who greet him with mild curiosity and a benign approach. Despite the handful of stories every year about a shark attacking a human, we know the truth: We’re the predators, and they’re the prey.

There is little here that was not already tackled in Rob Stewart’s 2007 documentary “Sharkwater,” nor in the more recent, less artful “Seaspiracy.” Though where Stewart painstakingly explained the beauty, intelligence and importance of sharks, Roth would rather that we love these animals simply because he does.
