Review Detail of asdasdssf in Harry Potter and the Secret Treasures

Problem with this fanfic that it just doesn't make sense. Mc is supposed to be reincarnated and know the plot. But author basically decided to stick to original plot, so what happens is that mc is artificially made retard so he can't change to plot (even though story tells us he is smart). And any small changes that actually happen, get somehow corrected so that plot again steers to originals. Nothing just makes sense. Mc ignores obvious solutions to his problems, just so that author doesn't have to bother actually writing something original. Honestly story is actually written well, but problem is that even if you can write, it means nothing if the story you are writing is nonsense. Maybe the most plain example is Prisoner of azkaban arc. All mc needed to do is to secretly go stun Peter, give him sleep potion or something, and bring him to Dumbledore so Sirius name could be cleared. Mc's plans were really bad in first place, but every time there was actually chance to do something for some idiotic coincidence it didn't happen, all to somehow preserve original storyline. Like when he gave peter to ron when he was raging, or when the map was opened.
