The scene wasn't great, but it wasn't appalling either. I agree that what should have been such an iconic moment was fluffed, but it doesn't ruin the film. In the context of the story it makes sense - Anakin has lost the one thing he sacrificed everything else to save, his true love.
And can I just say: I love those literary geniuses who slag Lucas for his writing, but then suggest their own alternatives such as 'Why!?!' or 'Aaaaargh!!!!'. Oh yeah - they'd be *much* better choices!
