Contains brief, but disturbing and gruesome imagery around the slaughter of dolphins in Taiji, Japan.
The movie is informative, interesting, and inspiring, but contains shocking pictures: blood-red water, fishermen striking blows, and dolphins struggling and dying.
Also, there's an almost constant tension in the film, an ever-present threat of violence.
The goal of the movie is to inspire audiences that something can be done, but sensitive and younger viewers might be disturbed.
This is a very emotionally jarring movie.
