'I was really moved by the performance'처럼 감동을 표현할 때는 수동 감정 형용사(moved, impressed, inspired)를 씁니다. 'focuses on', 'deals with', 'explores the theme of'는 작품을 설명할 때 자주 쓰는 표현이에요.

• •I was moved / impressed / inspired by → ~에 감동받다
• •focuses on / deals with → (작품이) ~을 다루다
• •It's supposed to represent → ~을 상징하는 것 같다
• •In my opinion / Personally, I think → 개인적 의견 표현
