Loads of top books were initially rejected and many authors wrote one outstanding book their other work doesn't live up to.That was precisely his problem. He was good at plot and terrible at everything else. Which is why his book was rejected multiple times. It was only until Perkins took him under his wing and walked him through lots of changes(often with Maxwell forming the prose himself, explaining why grammatically it made sense) was his book accepted to be published. I think with Fitzgerald lot of the criticism stems from the fact that his editor did lot of leg work on his behalf and that he never wrote any book worth considering after the Great Gatsby.
Having variously edited magazines and websites, I know full well that what someone files and what ends up on page can be very different things. But let's face it, 99% of people enjoy a book for what it is, without caring about the editing process.
You should give it another go. I still hate the Tempest after being forced to read it at 13 or 14.
