Don't change too much in the original. After the great changes, people feel less intimate and more unfamiliar. There are twists and turns in the original story, which makes people feel more real and closer. So as long as there is true feelings in the movie, the audience can scream. There is no need to care too much about science fiction. The war environment is just unrealistic for people nowadays, and the audience only pursues the overall plot.
Although the adaptation of this film is large, it brings a lot of regrets. But such an ending can't help but make people feel more desperate. Since it can't be a sci-fi blockbuster, it can eventually become a screaming youth romance. The only pity is that science fiction and love make the original readers lose that hope.
The details of the original work can touch people's hearts and are the greatest love of life. This is what people want. No matter what happens, even if the end of the world comes, the person you like still cares about yourself. This is the original intention of the original work, always putting love at the forefront. As long as there is love in life, everyone can be happy.
The content of the original work is the gradual progress of feelings, so that all readers can slowly put their feelings into it, which is an emotional explosion point. If this effect is achieved in the film, it will really touch everyone.
Movies need surprises, happiness and all emotions to be intertwined to form an emotional drama. If "Shanghai Fortress" is filmed according to the original work, this effect may be achieved, and the influence of the ending on the audience will also be greatly changed.
