Voldemort's character should be similar to Hitler's, arrogant, proud, and like to be unique. And Voldemort portrayed in the movie is like Hannibal in The Silence of the Lambs, a arrogant, withdrawn and talented demon.
Hitler and Hannibal are two different types of demons. Although Hitler was arrogant, he would not satisfy his arrogance by mocking and embarrassing others. Hitler is a person with high ability + high emotional intelligence, and has a wide range of appeal and influence among ordinary people. Hitler's actions were almost always aimed at realizing his own ambitions. Hannibal is also highly intelligent, and can easily see through others and calculate others. He played all the rules, morals, laws, and played tricks, deceives, and sarcasm to almost everyone. But Hannibal did not have the desire for power, nor the consciousness of fighting against differences, nor could he establish influence and appeal among ordinary people. Most of his actions are arbitrary, lacking a long-term and clear purpose.
In this movie, the plot of Voldemort dueling with several playmates at the wizarding school is the least in line with Voldemort's style. Challenging potential partners, taunting opponents, and slaying them with extraordinary magical abilities. Such an image is very similar to Hannibal, and such a personality would have no followers. Just like Hannibal, due to his super high IQ, he can easily see through others, calculate and calculate with each other, but this is doomed that he can only be a lonely devil.
Unlike Voldemort, he has a large following of Death Eaters and can build forces against the overthrow of the Ministry of Magic. These are not something that someone as eccentric and eccentric as Hannibal can do. Hannibal is just an anomaly wandering the world, challenging, mocking, playing in the world, being alone and comfortable, a ranger, and an outlier. And Voldemort should be like Hitler, arrogant but extremely rational, pretentious but not withdrawn, with appeal, followers, and charisma to others. That's Voldemort's personality, not Hannibal's.
