And all during the main storyline, she has constant and regular battles against overpoweringly strong foes that she subsequently defeats by having sudden epiphanies and bursts of power that result in brief, but revealing flashbacks to her dark and mysterious past that she has conveniently forgotten due to amnesia since episode 1.
She also develops a romantic relationship with her childhood friend, Applejack, that slowly develops over the course of the show in the form of filler character development episodes, but never really culminates until the latter half of the show.
Also, her reason for living is to seek vengeance. Reasons for seeking vengeance are revealed in episode 32 and are never mentioned again anywhere in the rest of the show. Ever.
I think it'll do a little better than Seinfeld did, but not by much.
I think that they should've gone the PPGZ route. Yes, the show was crappy as all hell, but it ensured that PPG got a foothold in Japan. MLP should be edited for the Japanese audience in order for them to better relate to it.
To be honest, I definitely wouldn't mind too much if The Unexpected Love Life of Dusk Shine got converted from a manga to an actual anime, even if it's cliched as much as it is, just to get the Japanese audience in on what is currently a Westerners-only fandom.
