The movie takes place in an entirely artificial world, where a Gothic castle crouches on a mountain top high above a story book suburb with a goofy neighbourhood where all of the houses are shades of pastels and all of the inhabitants seem to be emotional clones of the jetsons.
The main character, Edward goes on a major journey. From the beginning of the film we see scenes depicting how it feels if you are different and are amongst people who fit neatly into societies accepted roles. Edward is looking for love and understanding, which is something that you long for. He has been taken from his comfort zone to a more populated and somewhat scary environment. Edwards journey is learning how to trust, and how to fully understand that people with differences are sometimes better off alone.
Taken from his comfort zone and being put into a busy and noisy neighbourhood, Edward realises that there is going to be major changes in his life in order for him to adapt to his new environment and new ways of living. He is an outcast, trying to find his place in a world in which he does not belong.
He has significant differences in his appearance to the everyday person with 5 fingers and toes, instead he has sharp scissors as hands and an ashen white complexion. Burton uses this as a prop for discrimination, and that's exactly what Edward gets. He knows he is different physically but wants to show people that he can love and he does have feelings and its whats on the inside of a person that really counts, and this is what Kim saw in Edward.
