a a popular sport and surfing be like by many people . just after watch the documentary and i realize how dangerous it could be . in fact the surfer also scar of big wave . even somebody get kill by it . but they still keep on surfing and enjoy themselves . only brave people can do it . accord to what the surfer say and we can clearly know what they felt when the big wave come at them . you have to adjust to your best and avoid direct strike from the big wave . when you win it and that will obviously bring you huge satisfaction . the amazing cinematography can not be overlook . that be absolutely visual enjoyment . an excellent sport documentary . positive .
