Batmanization of Vader, you say?
Over-the-top drama you say?
STAR WARS was seen for years as "too nerdy", so the new marketing makes it "faster, more intense", so that it appears more angsty. You would surely agree we already had examples of messed-up characters' characters in the EU (expecially in comics).
It sucks just as mixing STAR WARS with things such as Angry Birds...
