Divide your paper into four sections. Label the sections "Effect," "Writing," "Directing" and "Acting" before the production starts.
Watch the production carefully. Pay close attention to every detail of the production. Note the actors, direction, scenery, lighting and sound.
Take notes after the production ends. Start with your initial reaction to the play under "Effect." If it was a comedy sketch, ask yourself if it made you laugh and how hard. If it wasn't funny, think what could have made it funnier. If it was a play, ask if it felt like a meaningful dream, whether it left an emotional impact or made you see the world with new eyes. If this was the case, consider whether you feel this was the playwright's intention.
Decide what particular aspects made the play leave the impression it did and write these under the proper heading. Questions to ask for evaluating writing include: Did I buy the characters' decisions? Was the dialogue nuanced? Did the plot keep my interest?
Questions for direction include: Did the movement of people on stage make sense? Were the actors properly motivated? Was the lighting and sound properly motivated? Did the settings and props distract from the story? Questions for acting include: Did the character connect with me, move me? Did I believe it?
Crystallize your thoughts by writing a review discussing the strengths and weaknesses of all these aspects. Include suggestions on how to improve what isn't working.
