This by far the a classic. I first saw this as a child of five and the image of the cybermen coming out of there tombs stayed with me and is why the second doctor is by far my favorite.
Im not going to talk about the story as that has been done by other reviewers, but about the DVD. I already owned the video and loved it but was disappointed by the quality. we have to remember the original medium it was recorded on was not high quality film but BW video. THe DVD did an excellent job of restoring the video to as near original condition. The old video look adds charm and character. THe extras are fine I love the alternate titles, the restoration feature shows the damage that was cleaned up, Damage that was quite evident in the VHS video. Another feature I like, not just with this video but others, is the use of an additional closed caption track to give behind the scenes info. All in all a fine job especially considering the age of the material. I Own a good number of DR Who videos and would buy them again on DVD on the strength of this release
