This screenwriter can ignore behavioral logic and universal morality, first give 70% or even higher proportion of black history to the characters he has poisoned, and then give a wave of highlights at the end to show his beauty. This routine is put on Sorin-30% of the optimizers are focused on face value and temperament. In addition, a merciless and comprehensive attack on mental retardation will make him a fool. And the result? Sorin's "Lonely Mountain" can't save the criticism of serious murder, and 70% or 80% of the flaws given by the screenwriter are fatal to the characters.
In the original book, Sorin is actually more like a leader with a little comedian temperament (although harmony is a passive attribute). At that time, thirteen dwarfs knocked at the door, and he was the one who was crushed at the bottom. In the face of his father's harsh questioning, he pretended to be stupid and begged for help. In fact, I have to say that Sorin in the original is more like Bahrain in the movie (Sorin is bigger than Bahrain). As for the conflict between the elf and sapphire, it is completely out of thin air. It was the screenwriter who forcibly applied the nonsense plot caused by the conflict between Tingge and Dwarves, which was the first beginning of Sorin's mental decline.
I'm not dissatisfied with the film adaptation, but I really think his level as a screenwriter needs to be improved. Back to the question, why do you think Sorin is a sand sculpture? Because he is in the movie, your feelings are not wrong. Of course, different people have different understandings of the works. The key is to look at the individual's mentality, just look at it, and there is no need to be serious.
