How do you evaluate the movie "On the Balcony" starring Zhou Dongyu and Wang Qiang?

The film is very good, but of course there are some regrets in the film. Although the new male protagonist looks cute, his jerky acting skills still limit his interpretation of the character, and his pidgin-like Shanghainese is not authentic enough. The audience is not able to feel the psychological impact of the character through his always dull expression. change. As for Zhou Dongyu's performance, at first glance, her appearance is too shrewd to convince the audience that she is playing a mentally retarded girl. But looking at it from another level, Zhou Dongyu's role is not just a mentally retarded girl, but Lu Shanshan in Zhang Yingxiong's eyes. After adding this layer of filter, her lightness and agility can be interpreted in a more reasonable way.
