I think a movie is quite different from a stage drama. For the latter I expect a stronger storyline with a more stronger character leading in the story. In the present movie the focus is however shifting between Chirsty and Joyce, from time to time. I would rather the director give me more hint that she is telling two stories in one movie starting from the beginning.
I appreciate the effort of the director in giving her best. House of Joyce is decorated in a way showing the character of Joyce, especially the tower wall. Costume of female lead fits her character too.
I hope you would make more movie-like movies.
