The ending of the submarine movie can be a bit confusing and open to interpretation. However, there are a few key elements that can help us understand what happened and why.
In the final scene of the movie, we see the main character, a young submarine captain, standing on a beach, looking out at the ocean. He seems to be in some sort of trance, and he appears to be seeing something that we, as the audience, cannot.
As the camera pans out, we see that the captain is standing on an island, surrounded by water. This could symbolize his isolation and loneliness, as he has been cut off from the rest of the world for an extended period of time while serving on the submarine.
The captain then begins to walk towards the water, as if he is being drawn to it. This could be interpreted as a metaphor for his own death, as he is walking towards the unknown and potentially dangerous depths of the ocean.
As he reaches the water's edge, the camera cuts to a shot of the submarine, which is now completely submerged beneath the surface. This could symbolize the captain's descent into the unconscious mind or his own personal hell, as he is forced to confront the demons of his past.
Finally, the camera cuts back to the captain, who is now standing in the water, with the waves crashing around him. This could represent his acceptance of his own mortality and his willingness to let go of the past and move on.
Overall, the ending of the submarine movie is open to interpretation and can be seen as a metaphor for the captain's journey of self-discovery and acceptance. Whether he is facing his own death or simply coming to terms with his own inner demons, it is clear that the captain has undergone a profound transformation by the end of the film.
