This Blu ray is amazing. Pin sharp picture, full HD 1080P. At just over an hour and a half, the film never lags, and the narration is superb by Patrick Stewart.
Just a note to those who already own the Blu Ray of 'Planet Earth' that the BBC released last year - around 10-20% of the footage appears to be either the same or similar, especially in the Polar Bear and Cubs segment.
There is enough new material to warrant a purchase, however. Watching through my PS3 console on a 42" Toshiba HD tv and the picture is pretty much pin-sharp in every scene, unlike the Planet Earth release that was a mixture of standard and high definition and often looked it!
