for this entire part I'm just trying to get across that no matter what categories you use they can be seen as both good and bad, I'm countering my own point on purpose because it is generally impossible to call writing good or bad using those categories.
I didn't necessarily say that simple writing is the same as lazy writing. It isn't and I personally love simple stories. and to add to my point before I'm addressing that you cant call simple writing bad nor good.
This is very interesting. I believe that lifeless characters, shaky structure and bad tones are what makes plot holes. Each of them can be overlooked on their own. They wont make the story that much worse but when put together they kind of create the plot holes themselves. Like when a character shows one emotion once but then the character becomes lifeless afterwards, this would be an example of both a shaky structure and lifeless characters. However if we removed the shaky structure and it went into more depth on why the character is showing said emotion it gets rid of the plot hole and can be somewhat overlooked.
and on the bad tones part I'm assuming you mean tones that don't exactly fit with what is happening in the story. (correct me if I'm wrong.) To be honest a bad use of tones can be incredibly bad but i believe a shaky structure and bad tones go hand in hand. When the tones are bed it can ruin the stories structure.
a really interesting argument though. let me know what you think.
