I'm going to have to vote for good writing on this one. It's probably a symptom of my long patronage of fanfiction.net, listening to young writers extol their storytelling abilities while I cringe at their abuse of the English language. I've left critiques for more than one author who angrily wrote back insisting "it deosnt matter how u wriet, u shuld read teh story an not B so mean abt grammar n stuff. Who cares?"
I once read a short story the plot of which was simply a person watching raindrops roll down their window-pane, which I think is about as close as you can get to writing about watching paint dry. But the prose was so beautiful, so haunting and thick with sadness, with beautiful imagery and a very poetic flow that made me as though I was being rocked gently to sleep while listening to the sound of the rain (in a GOOD way, not in a boring way), that I've never forgotten that short story. I can't find it anymore, which saddens me, but it resonated so strongly in my memory that it's stuck.
In the same way, there's a passage in one of my favorite stories ever, The God Eaters, where the main character is imagining his hometown in the snow. All he's describing is snow, fog, and buildings, but his wistfulness and the quiet, dripping peace of the place are so PALPABLE, it's stuck out in my mind as a uniquely beautiful passage.
To write something unique, you have to see things in a unique way, demonstrated in 'Zen and the Art of Motorcycle Maintenance': A student finds herself utterly blocked when it comes to writing a report about her hometown, so the teacher tells her to narrow it down to the main street. When she also fails to find anything to write about on the main street, he tells her to narrow it to a single building - town hall. This also fails to produce any inspiration, so in a fit of exasperation, he instructs her to write about a single BRICK in the front wall of the town hall. Later, she bewilderedly hands him an extensive paper she's written about the brick, saying, "I don't know what happened... it just started coming out of me" or something to that affect (I don't have the book on-hand for the exact quote at the moment).
Marcel Proust said "The real voyage of discovery consists not in seeking new landscapes but in having new eyes." So in conclusion, I say that a truly good writer can make any plot interesting as long as they present it with a 'new set of eyes', that is, in a unique and interesting way.
