Well...
They do say in every wild tale there is a grain of truth...... and before you all throw your contact lens cases at me!!!!... no I haven't seen the film but from the descriptions there is something to the beginning part of her post graft experiences...
Back when grafts were first trialled, they grafted people blind from birth or early childhood. And I mean they were grafting totally opaque corneas. Thus these people had grown up with a totally tactile sense of the world. Once they could see, they could not make sense of WHAT they were seeing. For example, they could not "see" the top part of a double decker bus, or a house. To them, these objects only had substance where they could feel them and their brains could not conceptualise parts of the image that they had not felt.
Some graftees could not cope and became profoundly depressed. They could only find their way around by closing their eyes, because they could not process what they saw. Others hated the fact that the real world was not as wonderful as they had imagined it! Its fascinating stuff!
Nowadays, of course, people are grafted as early as necessary and you do not find many people in this extreme situation. BUT, if someone did have visual sensory deprivation for that long, they would take some time to re-orientate and get the brain in gear to interpret what they saw.
As to taking on donor characteristics, this has been discussed for a long time and it probably reflects the psychological unease of some from having tissue from someone else. It IS hard to think you are seeing/living and enjoying a full life because someone else died and everyone does tend to have a wobbly moment re this.
The film has taken all this and gone several steps further, or several miles further it seems! However, it is a fantasy film and people will look at it on that level. It may even actually help to break the ice re talking about grafts and encourage people to ask what it is like and give you opportunities to explain your own experiences. They may, God help us, even think its "cool"!
However, I did totally crack up at the description of "she has your eyes"!! Now I have GOT to see this thing, just to catch that punch line!
