The fireplace dialogue in AotC I really did not think was too bad. It was a very uncomfortable scene because I believe it was supposed to be uncomfortable with his dialogue/pouring his heart out to Padme. Maybe it was that outfit of hers (yow-za!) 'A poet everybody, the laddie reckons himself a poet' (do you know where that quote is from?) People slammed Anakin for his 'you are in my very soul' speech, but think back to when you were young, trying to get your feelings across to a potential love, you rehersed things to say to impress and persuede her/him and in retropect it probably sounded a bit corny. But to Anakin's credit, it did work.
My idea of weak dialogue was in Padme's apartment, when to change the subject with Anakin, she says something to the effect of 'just hold me like you did on the lake on Naboo, when there was nothing but our love, no war etc. etc...' But maybe emotionally she was starting to lose it by that point and did not want to face the impending facts of things happening in her life and that possibly her decision made with him was not the most wise.
Dare I ask parson, where is home for you and what are you going to do when you get there?
