I think the 'Hayden acting ability' debate can never be settled, because it's a matter of opinion, not fact. I agree that he's been trying to modulate his vocal patterns, and at times it works - "Is it possible to learn this power?" being an example of where it works very well. But I'll say that he grated on me in his non-Star Wars films as well. And it bothers me, because I really WANT to like him. I want to be blown away by his performance in ROTS. And the minor dialogue in the trailer was encouraging. But I just rolled my eyes when watching 'Tragedy' and thought 'here we go again.' The one shot where he is hooded and looking angry and his eyes flit back and forth a little just looked to me like a 5 year old throwing a temper tantrum. Even his "noooo" just sounds a little dorky.
