Just what does it say about her (let alone just why DOES she fall for Anakin?) that she starts a relationship at a time when she is thinking of starting a family - with a Jedi who has some authority / killing issues, stares at her rather creepily and blames his 'father figure' for holding him back?
I'm only surprised that Lucas didn't have Anakin tell her that he's been having dreams that end with him and a m8 ruling the galaxy after offing all his pals/everyone he likes (or stares at) for all not having the same views as his...
Sometimes, in films good characters and actors can help iron over some the failings in the script - though Portman and Christiansen so far have failed, along with a very poorly thought-out script. I hope that Ep3 can rectify or rescue something out of it - or maybe there's a whole host of deleted scenes where their relationship is done justice.
Though I very much doubt it.
