it's cute not romantic, they don't see a child as a romantic link, in the future when they are old enough that may be so, but at the moment it is just a link to those they care about, a bond that wants to protect them. Almost like the Cullens feel about Renesmee, they inexplicebley, want to defend her from any harm. Imprinting is this 100 fold, it will later no doubt form another kind of a relationship. All I can say is that if I grew up with someone protecting me with their very life, not only would i find it very hard not to fall in love with them, but i wouldn't want to resist.
nooooooooooooooooooooooooooooo please don't they did this with SK's dark tower and it cheapened it. Don't get me wrong when graphic comics are in film format they rock, but to put a good novel into one and miss out all the subtle elements of the story, and concentrate on all the obvious ones is not a good move for this exceptional story.
