...Where can I begin?
Let's start with the good qualities this author has. She can hook people. She can get them interested in a story. She can write well, and she can write a lot. She is also a very good artist.
Now for the actual criticism. The author is fixated on her worldview, and has an extreme intolerance for anything that even hints of contradicting it. She cannot take criticism, and deflects all significant questions or simply ignores them. She is inflexible, and unwilling to admit that she might be wrong.
In her stories, she constantly proyects her own troubles into them. This is not necessarily a bad thing, but the way she has these problems "solved" -by having her characters drink a vial of "Potion" that magically whisks any personality problem they might have, and moving to some magical place where nothing bade ever happens- is more than slightly disturbing.
The ponies in her stories are out of character, which is standard fare on TCB fics, but they are so far off the mark that it's not even funny. The ponies here are seemingly incapable of evil -even to defend themselves- which not only makes them into a species of Mary Sues, completely ignores canon ellements, such as Trixie, the Flim-Flam brothers, Diamond Tiara and Prince Blueblood, and even the mane cast on occasions. On the flipside, humanity is constantly portrayed as an entire species of greedy, violent barbarians full of fanatism and hate, which is quite impossible since if it were true, we would have wiped ourselves out a multitude of times in 40000+ years of history.
Quite literally everything bad in her stories stems from humans. The HLF is human, the PER is composed of former humans, the pony jerks are descended from a former human... the list goes on.
And let's not even start on the subject of her Celestia, who screams God Mode Sue so loud the martians can hear it.
However, the true epitome of her attitude is the story Ten minutes: Aftermath. In it she completely diregards the personality of the main human character, makes the main conflict of the original story moot, introduces an unnecesary romance, and strips away the feeling of struggle that made the original so great. And that is why I so despise her stories: There is no struggle against the dark, no final moment of resistance, no finest hour.
And who likes a story like that?
