First, the Charms were amazing! Those alone would have probably ranked a 3 or 4.
However, the treatment of the Unconquered Sun and his panoply was stiff and not terribly imaginative. The Daystar chariot was rather... unneeded. His whole characterization seemed like an attempt to undo the damage to the Unconquered Sun's character which occurred after the 2E core. However, to me, it also demolished the ambiguity and make-of-him-as-you-will flavor that Games of Divinity left.
For a treatment of one of the defining characters of Exalted... it was unacceptable.
Oddly enough, I'd buy it for those Charms...
