What relevance do the buttons (button-eyes) play in Coraline as it never appears to be defined. For those of you who have not yet seen the film, then please do not read any further as the plot will be revealed. For those of you who have seen it, then please continue to read.
My thought was that it was because the Other Mother made the other world and thus used buttons as her 'signature', if you like?
Can anyone clear this up?
