Review Detail of Spelloyal in Godly crafter in DxD

I have mixed feelings about this fanfic. On the one hand, it's a face slap cringe fanfic where the author ignored an absurd amount of detail compared to the original material and just forced a scenario where the mc would be the "garbage" of the Gremory family. On the other hand it's an interesting fanfic about a mc crafter with really good ideas. If it wasn't for the last chapters I could probably ignore the beginning of the fanfic as water under the bridge as it seemed to have improved, unfortunately the cringe factor of the last chapters was more than 8000. In conclusion (no spoilers) if you like a face slap cringe story where we have entire chapters of the mc just giving the face slap and then justifying this fanfic is for you. I even believe it would be a good fanfic if the mc didn't have to do it all by himself, if the author let other characters around support the MC in those moments, so the scene doesn't become an arrogant monologue on the MC's part, it could be more interesting . If you don't like these cringe situations, this is still a reasonable and interesting fanfic to read, however you need to be patient to endure the forced slap face cringe chapters if you want to enjoy the fanfic.
