Harry Potter: A Certain Ancient Rune Professor of Hogwarts某霍格沃茨的魔文教授

This story is a complete dissappointment. It started really good, with a diferent aproach from other stories and an interesting mc.

The mc is a reincarnated person with a cheat ability that lets him master his spells faster. We also learn that he had an interesting time at Hogwarts while studying, as he had to defeat the whole of Slithering while there. At this point I was thinking, well, this character seems to be proactive and have some backbone. Man, was mistaken! Soon I discovered that I was pretty much the opposite...

As the story starts and one reads some chapters, some things start to become clear. The story follows canon events but for some reason the author doesn't want this mc to interfere with them, and does something that should not be done. He totally nerfs the mc and turns him into a complete incompetent whenever such events take place, so that he doesn't change anything.

The future knowledge that he has as a reincarnator doesn't seem to work well with the author's plans and therefore such knowledge dissapears and the mc doesn't remember even the most obvious of the events in canon. Therefore we often see him stumbling around wrong assumptions all the time...

Then something worse happens and suddenly the mc no longer has any drive to do anything, or any objective, or any mission/plan/etc. Nope. He gets relegated to a secondary role in the story whose only purpose is to help a little bit the golden trio, and nothing more. And from this point onwards he started to appear less and less in the story, and the golden trio started to appear more and more. Specially Hermione. There are many chapters that are entirely from her POV.

In the end I can no longer say that the mc of this story is Felix, as the author turned him into someone completely useless and does nothing important in the story. But most of all, because Hermione and the golden trio appear a lot more in the story than Felix himself!

As for plot advancement there is almost none. Many chapters are filled with irrelevant information that serves no purpose. Other chapters are simply flashbacks of the begining of the story that simply repeat what has already been said. Simply put, there are a lot of useless chapters that can be ignored completely.
