How is difference shown in the film and what is so unexpected about it? Is the protagonists' behaviour logical?
The film instead of showing "black" people and "white" people, etc.
it shows monsters and humans. In the film, though, it is shown a good side of the monsters is shown and not the bad one that we all thought they had. It also shows humans from their bad side trying to kill the supposedly bad monsters.
Dracula's behaviour can be characterized as normal and strange at the same time.That's because in the first place he is trying to protect his daughter from the humans, as he thought they where still bad and uncaring (not forgetting they killed his wife), but on the other hand he is acting fairly strangely as he sees that Jonathan is a good person and he doesn't let him do anything.He also hasn't seen the world for over 100 years, so he has no proof that the people will be as bad as they were so many years ago.
In conclusion, I think that Dracula's behaviour is logical, but out of date.
