** Possible Spoiler ALert **
The thing about hollywood is - it doesn't usually do 'deep', and this film has great depth, and can be seen at different, sometimes divergent levels.
The premise - as I saw it - is that a very old vampire, locked in a child's body, needs a human to protect and provide for her. The way she goes about this is looking for very young, potentially homicidal boys with no sense of morality, and a potential for extreme violence, and gradually makes them love her. Whether she ever feels anything thing for her protector is debatable, as every action she does, even to the 'accidental' glimpse of her nakedness, could be said to be contrived.
The film is even better the second time around, and makes me think I will have to give the remake a very wide berth.
I still haven't forgiven them for 'The Day the Earth Stood Still' remake
If your vision so exceeds your ability, then look to something closer.
