I give full marks to the special effects, although the plot is not very good. The whole drama is supported by special effects, I really don't know how to say it, but it's okay! Secondly, from the perspective of logic and human nature, compared with the embarrassing performances of many characters in domestic disaster films, the performance of these two heroines is very in line with the characters and performances under some adversity. Kate's character is free and easy, adventurous and heartwarming, while Lisa's character is a more cautious family type. Lisa was nervous at first, while Kate took on the responsibility of comforting her sisters, removing obstacles, and venturing out of the cage to contact the ship above, while Lisa stayed in the cage in fear. . . However, it is definitely boring to continue the film like this. Soon Kate is deficient in oxygen due to a lot of activities, and Lisa can only take over the task of finding the light in the distance. The plot begins here with a small twist. I have to mention that most of the heroic characters in European and American movies are timid and lack confidence at the beginning, but later they can exert great energy to shoulder greater responsibilities. Lisa seems to be this role in this film. The whole plot starts here, and Lisa is forced to take a brave first step. At the beginning, Lisa cried and told Kate that she was abandoned by her boyfriend because her boyfriend said she was boring. From the film, Lisa's character is cautious and restrained. However, in the face of life and death, she has to face the endless darkness and the sharks that appear at any time, out of the cage to find the person who dived to rescue them. Lisa has been terrified since she got out of the cage. She didn't swim far when a huge shark attacked her, and she instinctively fled into the rocks to avoid the shark. It can be seen that not only did the attack not frighten her, but perhaps she thought, so be it! Many times, people are not defeated by reality, but by the fear in their hearts. Once they have experienced it and overcome it, they will become very brave. Later, Lisa quickly walked out of the rock pile, and then actually walked to a cliff, where the bottom was dark and the light was not far away. I am very afraid of water. When I saw this scene, I was afraid, and subconsciously did not want to continue swimming. However, Lisa is obviously someone who has overcome fear and became stronger. She mustered the courage to swim over, and experienced Hardy returned to the cage with the rescuer's rope (the rescuer was killed by the shark). The last point is also the highlight and turning point of the film and where the deep exploration of human nature lies. The rope was taken, the cage was pulled back in half, but it broke, and the cage fell again. This time it was even more dangerous. Lisa's leg was stuck in the cage, and the oxygen for both of them had bottomed out. Kate had to contact the ship again to put down two oxygen tanks, and Taylor (captain) on the surface reminded the two that the reason why they did not give the oxygen tanks earlier was because there was a great risk of causing hallucinations in nitrogen anesthesia (here is a foreshadowing). In the second foreshadowing, the two sisters were waiting for the oxygen tank in the cage. Lisa spoke her heart out. Although the two were sisters, Kate was free and unrestrained and loved freedom since she was a child. The only thing better than Kate is having a "good boyfriend". It can be seen from this that Lisa's unwillingness is in her heart. In real life, those who have been compared by friends, classmates and relatives should have a little bit of sympathy. In her heart, she still wants to surpass "that person", even in one aspect. Kate came out of the cage to get the oxygen tank. When she was about to get to the cage, she was attacked by a shark and disappeared. Lisa was hoarse, but there was no sound, and her own oxygen was about to run out. Lisa was not willing to wait for her death. Although one leg was pinched, she still used the barb of the spear gun to replace the oxygen tank not far away with oxygen, and then waited for rescue. Unexpectedly, Lisa heard Kate's cry for help. It turned out that she was not dead, but was trapped in a rock pile, and was seriously injured and confused. Lisa heard the voice, and it was like a chicken blood: she thought Kate would die, but now she has renewed hope. She cleverly used the life jacket to inflate the cage to raise the cage a little, and desperately pulled out her legs, leaving deep bloodstains. Then she found Kate. In order to save her, Lisa resolutely took Kate to the surface regardless of the danger of being beaten by a group of sharks. In order to prevent decompression sickness, she slowed down at 30 meters and stopped at 20 meters for 5 minutes. Sharks fight all around. Finally, when the signal stick ran out, Lisa took off the diving equipment of the two and quickly surfaced. Just as she was about to be rescued, a huge shark grabbed Lisa's injured leg and dragged it into the sea. However, Lisa was already like a goddess of war at this time, and she was not afraid at all. She directly plucked the shark's eyes with both hands, and the shark was relieved from the pain, and Lisa took the opportunity to return to the sea. The two were rescued, Lisa's legs were bloody, but she still smiled, looking at her hand that was scratched when she was holding the oxygen tank, and smiled happily. If the film ends here, it is actually a very good film, but unfortunately the previous foreshadowing is useless, and it loses the discussion of some things in the heart of the characters.
