What did F. Scott Fitzgerald achieve by using Nick's point of view to tell Gatsby's story?

By using
a so-called "minor character as narrator" point of view, the author is able to inject
his own commentary on theand events in the story without interfering with the dramatic movement.
In other words, the author does not become an "intrusive author."has plenty to say
about everything and everybody in the novel. He is a judgmental type of person, although he
claims to be very broadminded. Fitzgerald's only other alternative would have been to use the
"omniscient third person" point of view, because he could hardly tell the story from
's, or 's, or 's point of view. If the author had tried writing his story as the invisible
omniscient narrator, he would either have had to leave out a lot of the commentary on his own
story, or else he would have had to be an old-fashioned intrusive author. That might have made
the novel longer and more episodic and slower-paced. Fitzgerald was a young genius and might
have written a brilliant novel in that alternative manner, but Nick Carraway as the minor
character narrator seems like the right choice.
