"The Great Gatsby Revisited" Response

I have only read The Great Gatsby once.  Maybe I should read it again, because I might be able to understand much more about the text.  The eyes of Dr. T.J. Eckleburg were one of the most intriguing parts of The Great Gatsby to me.  As I read the novel, it was clear to me that the eyes were a symbol, but I could not decide what I thought they symbolized.  Mr. Wilson acts as if the eyes were the eyes of God.  I am not sure if they represent the eyes of God, because Wilson is the only person who thought the eyes were like God's eyes watching everyone; some of the worst events in the story happen under the gaze of Dr. T.J. Eckleburg.  No one else in the novel seemed to think the eyes symbolized anything, they just seemed llike a pair of faded eyes to them.  The fact that the eyes are located in the valley of ashes seems important to me.  The eyes of Dr. T.J. Eckleburg are located in a desolate area of gray ash.  The valley of ash seems to be where the superficial areas of the Eggs become real.  The crash happens on the road overlooking the valley of ashes, and in Manhattan, Tom hits Myrtle, and Gatsby confronts Tom.  Even when Mr. Wilson goes to shoot Gatsby, which he does in West Egg, he is coming from the valley of ashes.  So the eyes lay in a barren "valley" that seems to spur bad incidents.  According to the blog post, the eyes "[disturb] the reader with a sense of formless moral scrutiny."  I did understand the "moral scrutiny" part, but I do not get how it is "formless," because the form is the eyes of Dr. T.J. Eckleburg.  If the eyes symbolize God, or moral scrutiny, why does Mr. Wilson ignore them when going to shoot Gatsby?  Maybe the death of Myrtle caused him to lose faith in God, or the symbol of God.  The loss of the meaning of the green light, another symbol, occured also, when Gatsby told Nick about what the light meant to Gatsby.  The conclusion I have come to is that the symbols are important only if the characters allow them to be.  I wonder if Fitzgerald  thinks it is good for characters to give the symbols meaning or not.
I know we are supposed to "respond" to this blog post, not evaluate it, but I just want to say that I did not like it.  I have not seen the movie of The Great Gatsby, so I am not counting the fifth point the author makes, but I thought the third and fourth points were the only insightful ones.  Nick makes a long point talking about how the story was a tale of the West, so I figured it was a tale about the West, even if I did not know why.  The author gives examples of Fitzgerald's great sentences, but says that she cannot describe how they are great.  That is not very impressive to me.  I am not saying I could describe the greatness of the sentences, but all the author does is say that the sentences are in fact, great.
