It may be that this is the best picture quality they could get from the source material, but it's a big disappointment after the great picture on part 2. The picture is very soft throughout.
Maybe picture couldn't be helped, but the extras could. None of the extras from the previous release like the audio commentary have made their way over. What is there, is okay, but like part 2 it's missing a good solid documentary.
Get it if they release the rest on blu and you want to complete your set, but as it stands, if you already own the DVD, this isn't essential.
