Lets preface this by saying that Ive never read the book.
I found Nick entirely sympathetic; he was the only real sympathetic character in the thing, and also the only one to which nothing dramatic really happens, which left me basically not caring at all about the story - the only character I cared about was the narrator, and hes just kind of being there the whole time, not doing anything. Even not having read it, I did get that theyd obviously misplayed Daisys character - she felt like she had no agency at all, and was fairly honest most of the time, so I couldnt understand how one could describe her as responsible for her own destruction.
Was Gatsby meant to be a protagonist? Because I disliked him almost as much as, if not more than, I disliked Tom. He was a deluded, obsessive con artist, and seemed like he had possibly even fewer moral qualms than the obviously detestable bad guy.
The visuals at the parties were awesome, although I wasnt sure about the anachronistic music and choreography choices. I think Id prefer to have seen it played more straight, with period music, at the very least.
