I mentioned reading this a few weeks back and that a full review was on the way. It's finally up at Spectrum Culture. Zona was a great read, illuminating in its anecdotal production details but best for Dyer's beautiful, sometimes poignant thoughts on one of the greatest of all films. There are some hiccups and digressions that grate, but for the most part this is one of the best books on a single movie I've yet read. Highly recommended.
