How can you evaluate the character's journey without reading the whole story?
If the plot for example is "character fights to survive" and eventually dies, there's no point for me reading it.
If Lord of the Rings ended with Frodo failing and Sauron winning, I'd thrown the book away.
How would you even know what the plot is supposed to be? It seems pretty presumptuous to assume that reading the end of the book is sufficient to make an informed judgment about everything that went before. For example, if you read just the end of Moby Dick
, how would you know how much of what happened was Ahab's fault?
