¶ … Shape of Things: Theatrical Convention from Class: Suspension of Disbelief -- the audience is made to believe that a man or any person for that matter could become so obsessed with a single person that they are willing to completely change themselves, including having plastic surgery and destroying their interpersonal relationships for a person whose only appeal to them is a sexual one.

Potential Convention: Given the subject matter of the play and the heightened emotions the ending portrays at least on the part of one character that I would try to have the actors deliver their dialogue and their attitudes as realistically as possible.

In the Blood:

Theatrical Convention from Class: Pathos -- the audience is meant to feel sympathy for the main character of this play and to understand her sense of desperation and her inability to find a way to preserve herself and her sense of dignity and also support her children.

Potential Convention: Due to the highly tense nature of the play, it might benefit best by containing the setting as much as possible to a single setting, such as directly inside our outside the home of the impoverished family.

Wit:

Theatrical Convention from Class: The play relies heavily on singular perspective of the dying woman, namely the soliloquy and her direct discussion of her situation with the audience.

Potential Convention: Because of the isolated nature of the character and her disease, the theme of the play would be helped by having her physically isolated on the stage, such as by creating a large space between the main character and everyone else, including her doctors.

The Goat:

Theatrical Convention from Class: Satire -- the play deals with a man's relationships with a goat but this taboo could be any sexual feeling which the...

Throughout history, plays have been written on a multitude of subjects and with a wide array of tones and themes, but one thing that appears repeatedly regardless of subject matter is a commentary on the nature of existence. Human beings have lived on the planet Earth for millennia but it is as yet unknown exactly why people are here and exactly what it means to be human. Regardless of why a play was written or the subject matter of that play, one thing that echoes throughout all plays is an attempt to understand humanity or to comment upon it. To make a comment on humanity that the audience and see, understand, and internalize is the ultimate goal of a play and the greatest potential a play has which can be seen in the works The Shape of Things, In the Blood, Wit, and The Goat.
The theater can show a very dark side of humanity which people do not want to think about but which nonetheless exists. In The Shape of Things (2001), a young man named Adam has his entire world destroyed by Evelyn for a graduate studies project. She cajoles him into severing friendships, into severe body modification, and into a sexual relationship which he believes is based on emotional intimacy. Films tend to show the brighter side of humanity and exhibit happy endings where boy meets girl and real-world traumas seldom reach them. This is not reality. There are harsh people in the world just like Evelyn and foolish people in the world like Adam. Theater's potential is to hold up a mirror to society and show some of the things that people do not want to admit exists.
