So what's the deal with the last one?
"I still blame his dad for the death of my mum - execute both of them!!"
TBH these kind of changes scream of a touch of "Lucas" to be honest, toning down or over-explaining elements of the trilogy. Surely the idea should be that that Vader only really starts to turn after he has met his son? 20+ years have passed since Padme's death. Vader is supposedly feared throughout the galaxy. Making him 'human' and showing remorse for his actions too early takes away from his reaction at the end of Jedi.
Just my 2p worth.
