@nfzeta I mean, I would say the fact that I have to or even CAN assume anything with a plot point this huge and important is bad writing. "He's not operating under common logic anymore" is 1) a cheap explanation and 2) just wrong. Everyone still operates under logic. Rules are established - and aside from reality bending gods - they have to be adhered to. It doesn't matter how broken the character is; they cannot have attained that strength or be using it in a way that doesn't work with the established rules. Not establishing rules beforehand is less bad writing and more cheap/lazy writing (which is arguably the same thing). When you're writing fantasy or Sci fi or whatever you have a responsibility to establish rules and world building and then adhere to them; that would be good writing. I don't see how the author can turn this into anything but worse writing. The very angry villain isn't likely to explain his full power set and how it makes any sense (which in of it self would be out of character and bad writing); a retroactive flash back is just stupid; and that's not even addressing the fact that when an all powerful antagonist like this is introduced and they kill tons of main and side characters there are VERY few ways to turn it around and NOT get bad writing. Continuing this story means losing the lifeblood of the Manga (the companions and side characters); solving this means: a) stupid power up (destroys pacing and the literal ONLY REASON WE HAVE A STORY) b) time travel shannigans c) another reincarnation starting the whole plot and story and character development for everyone but the Mc from 0 and probably making things worse (getting rid of the improving relationships). This is bad writing at its finest. Even if it wasn't it's STILL bad writing because it leads to bad writing and there's no good way out of this for the story. No matter what happens the author has permanently derailed and screwed their initial story (which will piss most readers off seeing as we're nearly 50 chapters in). Anything the author could do to solve this would still be bad writing because it would make the whole event irrelevant and meant I just wasted my time completely. The author physically cannot solve this without it being bad writing because of how he setup the story and played this chapter.
@Ryu12 even in the case that makes sense and there's no BS (I say that because reading your comment I thought "Okay I didn't remember that" but then immediately thought "Okay but still. Why though?" Why test a ridiculously unfair and insane punishment? Sure they TRIED to keep him harmless, but if they treated this as an experiment they should have known ANYTHING could happen. And again why even risk that when there's literally NO benefits whatsoever. There would never be a reason to do this punishment or just killing someone or locking them up. Mage association still would have to be completely mental to have done this (still manufacturered conflict and therefore bad writing. And again anyone well versed in research knows you don't do the practical experiment without TONS of theoretical and testing to be prepared for every outcome and know it's completely 200% safe), that's just a single talking point. Bad writing encompasses SO much more than just things making sense (which they don't here). Consistent plot, good pacing, nice character development, realism, good world building, effecient use of characters, and way more check marks all need to be met for good writing. If the story doesn't reach them... It's bad writing (and there are varying degrees to that. Most have good writing at times and bad at others).
This would be bad writing for so many other reasons. 1) it completely details the initial story aand premise. We've had a specific plot for the longest and a good story should strive to abide by that. Completely throwing that away because you think it got boring (instead of just writing that better) I bad writing. Readers came to this series for its initial plot; not to see all that go away. Making the main character have completely unreasonable thoughts Is bad writing (I.e "I created this monster by not letting him kill me and my friends earlier and letting the magic association handle him like they were high..."). Destroying large portions of your cast all at once is generally bad writing. This is where we get into the "generally leads to bad writing" stuff. Death should NEVER be used lightly or massively for main characters. Killing characters mean they can't be used again, you poss readers off, and the only benefit you get is a few scenes of reactions generally. You can bring characters back to life but that just cheapens the whole concept of death (and lowers all stakes).
A huge HUGE HUGE NO NO for any writer that doesn't hate themselves is to NEVER EVER make an all-powerful antagonist (or one with an insanely huge gap to the Mc and bent on killing the MC Immedi). The options a writer has to resolve this are just terrible. 1) use time travel. This is a really cheap trick. It essentially undoes the entire plot and is basically I couldn't think of anything else 2) a random huge power up for the Mc. Again cheap (all of these are cheap) and terrible for pacing and character development. 3) roll with it. This one is worse than you seem to belive. In a situation like this the author is forced to undo and destroy all the character development he did for other characters, all the world building, the plot progression to this point, and everything to make some new story out of the ashes. There's just no good way for this to go moving forward and that in of itself means bad writing. Even an all powerful protagonist is generally a bad idea for writers. It just makes it so ridiculously difficult to have actual conflicts (and every good story NEEDS conflict). Even isekai don't make the MC fully all powerful and when they do they largely get away with it by not having a serious plot (a serious plot and legit God Mc is a quick way to write a bad story). This just generally makes it harder on the writer to write anything but a bad story
Beyond all that a good writer knows how to stick to their target audience and initial genre. It's not difficult to go completely off the rails and ignore that. It is shitty to readers who came to this series for a specific reason. I'm clearly talking too much on good or bad writing; just as in a writing class and someone who enjoys it greatly that's not something I can let go easily. Ultimately it doesn't matter if the writing is good, bad, great, or whatever. It's if we enjoy it or not. If you like this development that's all that matters. I'd delete this having come to this conclusion, but I already wrote all of it and that'd be too depressing
