Question

and also the conclusion...

Answer 1

The major theme of the film was how, due to cultural assumptions, people of different types are still unable to communicate to each other despite living in a modern world. The movie attempted to make each culture as human as possible by including culturally-transendent behaviors that all audiences could understand and relate to. Underneath the many different cultures and disabilities, these people are all simply doing what all humans do- a man worrying over his wife, a nanny taking care of children, young boys trying to better each other, teenagers trying to catch the attention of the opposite sex, etc. However, cultural assumptions and suspicions held against them prevent such an understanding, revealing the struggles with communication due to stereotyping that we still have today.
