A great concept that goes astray in the early pages but resurges with great intensity in the first act. Gets beat up in the middle and dies in the third act. A miraculous plot twist saves it in the climax and it gallops away victorious at the ending.
A perfect plot, executed perfectly throughout its beat sheet until you get to the end and realize the concept was flawed. Chokes on its own poison.
A great concept that seems to lack plot, but you persevere, ignore the doubters and finish. Half your readers love it. The other half don't understand it.
