The parents' guide to what's in this movie.

Positive Messages

Clear messages about ravages of climate change, specifically in the sea, and possible negative outcomes of genetic engineering. 

Positive Role Models & Representations

Strong female characters: leading scientist/hero is smart, resourceful, loyal, brave, compassionate; African woman, native to the film's setting, is determined, extends herself to help others. Archvillain is relentless in his pursuit of task at hand, cruel and authoritarian. Ethnic diversity.


Violence, frequent suspense. Expected shark mayhem: almost all of the cast is killed (eaten, sliced, bitten, beheaded, torn limb from limb by sharks). Fierce hand-to-hand combat between heroes and villains. Explosions, drownings. An island village is attacked by sharks and men: fire, collapsing buildings, flooding, death.


One kiss. Skimpy bathing suits accentuate breasts.


Occasional swearing: multiple forms of "f--k," "s--t," "bitch," "ass." 

Drinking, Drugs & Smoking

Beer and shots in social settings.

What parents need to know

Parents need to know that Deep Blue Sea 3 is the third in a series of stand-alone horror-thrillers in which humans tangle with powerful sharks. Neither Deep Blue Sea 2 nor Deep Blue Sea 3 is a sequel to the original; however, in this one, the genetically engineered sharks that were created in Deep Blue Sea 2 are on the move again, coming up against a new cast and story. The highly suspenseful, vivid, and sometimes over-the-top action includes decapitation, dismemberment, attacks on unsuspecting scientists and technicians, and lots of blood and gore. Explosions, fire, flooding, and human hand-to-hand battles kill almost everyone the sharks can't get their jaws around. Swearing is heard occasionally: "f--k," "s--t," "ass," "bitch." There's one kiss and some revealing bathing suits. Beer and shots are consumed in social settings, never excessively. Amidst the mayhem, the film has a strong, wise female hero, and delivers sound messages about the dangers of climate change and genetic engineering.

What's the story?

Three bull sharks glide side by side through the Indian Ocean in DEEP BLUE SEA 3, heading toward an almost abandoned island village off the east coast of Africa. Living on Little Happy Island is Emma Collins (Tania Raymonde), a scientist who carries on the work of her deceased father. Concerned about the changing ecosystem, Emma, with a small team, researches the effects of climate change on the habitat's bountiful species, and great white sharks in particular. The humans and the powerful fish coexist, and the work is fulfilling and important. The first sign that something is amiss in their world is the discovery of two great white sharks who have been attacked and killed by an unknown predator. Soon after, a ship arrives carrying Richard Lowell (Nathan Buzolic), a former colleague of Emma's, and his crew. Richard needs Emma's help. He's tracking three bull sharks who are known to be extremely dangerous. They must be captured and taken back to the research facility from which they escaped. Reluctant at first, Emma agrees to help her old friend, until harrowing and mysterious events begin to happen: a dismembered arm, the disappearance of a local fisherman ... it quickly becomes clear to Emma that there's more to Richard's mission than he's been willing to share. 

Is it any good?

Striking images, along with quality underwater footage and above-average performances, elevate this third franchise entry; it's watchable in spite of the often ludicrous story and over-the-top gore. Rooting interest is strong for the lead scientist in Deep Blue Sea 3. Tania Raymonde appears as comfortable with the action -- and there's lots of it for her -- as she is in her more intimate scenes with friends and co-workers. It's interesting to note that very few of the mostly sympathetic fish lose their lives in this film. Unfortunately, that's not the way it works for the humans who have encroached on their saltwater neighborhoods.

Talk to your kids about ...

  • Families can talk about the violence in Deep Blue Sea 3. What emotions did it evoke for you? Was it terrifying? Exciting? Silly at times? Memorable? Why is it important to understand the impact of violence on kids?

  • In this movie, the filmmakers make both the bull and the great white sharks sympathetic creatures, even though they're destructive. Humans are the villains. Did this story alter your preexisting attitudes about the animal? How did it help you understand the natural place of sharks in the earth's ecosystem? 

  • Emma is extraordinarily heroic in the movie. Think of three positive character strengths that describe her (e.g., courage). Pick one of those traits and talk about why it was important to the story.
