The primary questions to ask yourself are: How well did the actors embody their roles? That is, who did you feel acted skillfully (or not) and what did that actor do (or fail to do) to successfully perform their part? Additionally, what did you learn that you could apply to acting your final scene?
You should freely and strongly express your opinion regarding the acting: what did you like and dislike? However, you must justify your position by (a) analyzing the performance using the terms and techniques learned in class and (b) giving evidence from the performance to support your opinion. Be specific: talk about exact moments in the play that demonstrate your point.
