Visually, the film has moments that are really impressive. While a few of the scenes — the dolphins alongside the whaling boats, Nantucket in the distance of Chase’s home — fall randomly flat with their CGI, the work done on the white whale is first rate. Seeing it dive beneath the boat and turn it into kindling looks excellent, as do its other appearances. The sense of scale between all the whales and the boats really drives home how dangerous this profession was.
