''Hotel transylvania''

How is difference shown in the film and what is so unexpested about it? is the protagonists' behaviour logical?

There are many differences in the film, but the main difference is that the monsters are afraid of people.In the reality this is different because the people are afraid of the monsters. The most unexpected thing happens at the end when a human marries a monster.This is not reality, but maybe the director wants to show that the people fall in love regardless of their type.
The behaviour of the protagonists is not logical expect (except?) Dracula's but in the end he changes. I think that Dracoula is afraid of the people because they have killed his wife.I think that Dracula fears people far more people than his daughter because he has been in danger because of them.Also, I believe that the behavior of his daughter was logical because she just fell in love.Finally,the boy was confused and did not know what to do.At the end of the film,everything went all right.The daughter and the doy married and Dracula was very happy.
