Although it took me a while to read it (mainly because I got an e-reader in between...), it was a surprisingly short text. I mean that, knowing it was a classic and all, I expected it to be longer. But short it is, and concise, and really interesting. 
 The main characters are quite complex in nature, and I'd actually love to take a class in Literature to see how everything is broken down. One thing I will do, though, is reread it someday. Because I liked it. And it was well written. And I think I can get more out of it through a second reading. 
 Oh and I ship Nick -> Gatsby.
