Even if you are not an avid theater-goer, attending a performance cannot pass without a trace for you - dramatic art is created in order to make you think and not leave anyone indifferent. Whatever requires you to give feedback on the play you watched, make it complete enough - after all, only thanks to the feedback from ordinary viewers, and not from theater critics, the director and actors (and sometimes the author) can understand whether they have managed to convey the meaning of the work to you.
A review differs from a review primarily in that it is based on your own impressions. Feedback is always subjective and individual. Be as honest as possible. At the same time, try to be extremely polite - even if the scenery seemed miserable to you, and the acting was dull and insincere, report it correctly, without trying to offend. The superlative degree and definitions like "magnificent", "amazing", the abundance of exclamation marks will also not decorate the review, but rather make you suspect you of exaggeration. Your opinion must be justified - unfounded statements that the performance is bad or good will not say anything about it to those for whom you are writing a review.
There is no clear roadmap for building a review, but a few key points can be highlighted. Comment on the actors' play, directorial moves that seemed unusual to you. There is no need to retell the plot of the play. It is better to note what struck you, found a response in your soul, and what, on the contrary, did not cause any emotions. Tell us how the characters embodied by the actors corresponded to your ideas about the heroes of the work.
Do not be afraid to seem ignorant - the review does not require a thorough knowledge of the laws of theater, a thorough analysis of the director's work. Describe your own mood: what it was like during the viewing, how much it changed by the end of the performance. You may want to compare the performance you watched with other productions of this piece, if you've seen them before.
Imagine that the other person will decide whether to watch this show or not, based on your feedback. Let the one who reads it, imbued with the atmosphere in the hall, the feelings of the audience, want to see the same thing as you, or decide not to waste time in vain.
