So, of course I had loved The Great Gatsby when I read it. Before I went to see the movie I knew one of my best friend (whose taste in general I admire) loved it. And also, it has Decaprio, who can do a good job.
So we go and find some terrible music but quite a good movie. Good screenplay, dialogues chosen out of the book, not too many twists to the original story and as silent in it's message as the book. I think this was the winning stroke for the movie- it did not dictate any opinion, just like the book. Some people might just go and come back with the idea that it was a tragic story of a rich guy.
And they can live with that, while I will continue to admire Gatsby and Decaprio, even more now.
