the complete dialogue with Grievous ('cause I like TCW tv series so I find it fun it really is the very first time they meet),

I know Hal said in his commentary that the Grevious-Anakin interaction was generally unhelpful as they don’t see each other again, but I think that it works in that a later confrontation with Grevious is just another thing the council takes away from him. There’s set up for him and Obi-Wan to face Grevious again, and the council taking Anakin away from the promise of that, to do something unethical, is just more fuel for his later turn.

I also like Anakin spinning because it’s a good trick.
