The disc itself is of the highest quality. The subwoofer does not get quite the workout as you would expect. This is especially noticible in the scene where two policce cars crash to the ground. The gain on the audio is not overwhelming. Again, unlike most films of the special effects SciFi genre this film does not assault your ears.
Extras are a bit light but the ones there are enjoyable.
Mostly, the deleted scenes were expository in nature. They fill in a little of the relationships between Jean, Scott and Logan as well as foreshadow the intent of Magneto's plot. This is definitely a DVD to get and enjoy many times over.
