Did you mean Emily's charachter was supposed to be American
Ekua?
I can't imagine why they would change that. Britain is the place where trains actually drive right past ppls houses ( I remember from when I was there) in America trains tend to almost always go through seedy neighborhoods or industrial settings. It would be very rare to go past middle class housing. That is disappointing. I can't imagine that story in America
or it being shiny. It should have been very everyday type people and filming, lighting and sets.
