Well, i rekon its best to split it up into the different levels:
Composer:
-Takes his own imaginative journey within his mind, (linked to inner journey), the fact is they probably had this journey within their head then felt strongly enough that they decided to produce a film about it.
Audience:
-Is shown a possible future, effects of science (negative) blah blah, may change their opinions on the development of new technologies etc... Or they may support it- they support the enhancement of humans (resistant reading- possibly Nazi??) Its good to show some different possible readings, as it is INSIGHTFUL AND SOPHISTICATED
Characters:
Im too tired to do this for you, how do the characters change throughout the text?? U have to answer this as i watched it ages ago- But to start I know that the girl decides not to hand him in -she is changed by talking with him-, and when they do the final swim, his brother decides sees that he is not really an 'Invalid" as society portrays him, but is capable human... His brother HAS BEEN CHANGED
ok well thats it, cos 2 half yearlys tommoz :'(
