It just seemed to me to be a great story, set back in its time but something that seemed to have relevance for our time. Now that the film is coming out, it looks like we're back in another time where repression of expression is all the rage.
A man of action forced into a state of thought is unhappy until he can get out of it.
I don't care how good a song is - if it holds back the storyline, stalls the plot, your audience will reject it.
