re: The Great Gatsby, worth the watch if you've read the book?

I thought it followed closely for the most part. (Granted it's been about 6 years since I read it) Leo is Leo and has a really good performance. Edgerton was phenomenal. Carey Mulligan was meh as Daisy. Sometimes she was good, sometimes she was bad. Tobey McGuire was boring but I couldn't quite figure out if that was purposeful or not considering Nick isn't the most intriguing character anyway. Some ppl complained about the extravagance, over-the-topness that Luhrmann used but to me that falls in line with the book.
