There exists a pair of lines in the song "Don't Let's Start" by They Might Be Giants that I find darkly amusing. They go like this:
"No one in the world ever gets what they want, and that is beautiful. Everybody dies frustrated and sad, and that is beautiful."
This sums up the book rather well, and that is approximately WHY I am not as besotted with it as I had hoped. There is nothing uplifting about it. Nothing that made me feel as if it had anything remotely resembling a point. It negates my liking for Nick, Jordan, Daisy, Gatsby, and the dude with the owl eyes. It just makes me wonder what the point was. Which isn't beautiful.
All that aside, it's a really quality piece of capital-L Literature, so if you don't need books with a solid point to them, you may love it.
