Great movie.
I loved the book, and I liked the movie's take on the story. I loved the visuals, especially of the "valley of ashes."
Leo did a great job playing an obsessed simp with an inferiority complex.
I'm going to be honest though: Carey Mulligan did a nice job (I'm a fan of her work in general), but she is nowhere near pretty enough to play Daisy.
They needed a classically beautiful knockout, not someone who looks kind of cute on a good day
