My goodness those clone lines both sound and feel off.
As for the removal of the grevious line, I get it since it didn’t really make sense when you think about it.
If one was to add something to it to extend the scene or at least make it feel not so “cut,” having Grevious say something like:
“You fool! I’ve been trained by Count Dooku to deal with your jedi arts.”
Or something like that to extend the shot. Actually, something like that would have been better originally since I didn’t know Dooku could extend 2 more arms and spin them. Amazing.
