The title of the movie says a great deal about the obsession with perfection that dominates American social structure. Based on its continual presentation of characters seeking perfection, which theoretical perspective can best be used to explain/understand the choice of this particular title?

Symbolic Interaction Theory.

Explanation:

Symbolic Interaction is the most important theory in sociology that defines the principle that there is a relationship between the way a person interacts with his/her society and the meaning that he perceives from this interaction about something.

The theory of symbolic interaction was proposed by George Herbert Mead but the term was named by his student Herbert Blumer.

For example, one knows smoking is bad for health but with his/her interaction with the society he perceived the meaning of smoking as a cool thing.

In the given case, the title of the movie and the obsession with perfection in American society is an example of symbolic interaction theory.

The American society is perceiving about perfectionism based on their interaction with the movies and media.

So, the correct answer is symbolic interaction theory.
