The problem I had with imprinting is very similar to what's already been said - choice being taken away, Jacob's blurry role of father/brother etc. But I did think it was a unique idea, and I often wish it could happen in real life!! Wouldn't that be easy!
I just couldn't understand why it should be possible on young children. I mean, I know that it's said over and over in the book that when they're kids it's not romantic at all- but the weird thing for me was that the imprinter does know, and intend, for it to become romantic at some point. When is that point? When they get impatient? Or a certain age? : / It just weirds me out somewhat when the children are involved.
