Why does high fantasy work in manga so well? What's wrong with the west!!? Maybe it's like you said 'lack of originality' so comic readers become used to the disappointment in fantasy comics and move on... I dunno.
Nice start... I am eager to read and discuss more!
Adding this fore my reference...
The term high fantasy (also epic fantasy) generally refers to fantasy that depicts an epic struggle between good and evil in a fantasy world, parallel to ours. The moral concepts in such tales take on objective and absolute status, and are not relative to the one making the judgment. There tends to be few shades of gray; the heroes are unambiguously good and the villains are unambiguously evil.
