Hi Jeanine,

If you use the word implied here, you are changing the meaning of the sentence. Imply has the sense of suggesting without making it obvious - a sort of underlying indication but that's not what I meant in this sentence. The film described itself as being about the Civil War but in fact it mainly concerned a love affair and so I used supposed to show that's what the film should have been about.

Hope that makes sense.

Alan
