This Two-Disc “Diamond Luxe Edition” of Gravity is a quality release though this should’ve been what was released originally. What you get over the original version are a couple new features including a 42-minute historical featurette and the new Dolby Atmos audio track which is a fine upgrade, though the original DTS-HD MA 5.1 track was pretty darn good on its own and Atmos takes it to the next level.
