This is an example of a great movie on HD but I didn't notice so much of a change in Blue ray version. If you already have the HD you don't really need to get blue ray. This movie is a five. I gave it four stars because if you already have it in HD then you could save the money. On the other hand if you have no version at all and are looking to buy for the first time the movie is a five and I would get blue ray.
