The “Nooooooooo” isnt something I have a problem with, in theory.
Its the application.
It just felt flat.
I think they should have done it in a way so Anakin could of had his big no scene before the suit, so at least you could have some emotion.
Now whether Hayden could have delivered, I dont know.
The “No” is one of those tricky lines that, if done well, can tug on your heart strings, and if done poorly, makes you roll your eyes. In ROTS, it was sadly the latter.
Other than the “No”, I really think my only real complaint is the casting decisions on Anakin. For kid Anakin, eh, yeah I guess its hard to find good child actors, so Id let that slide. But cmon, even though it was Lucas dialogue, HC’s delivery just was awful in almost every scene where he needed to emote something other than crazy lava burning hatred.
