Not a bad release, but I wasn't at all pleased with the picture quality on the main feature, which at times got pretty grainy and had a line running down the left hand side on a light background. My tv has a picture quality option which can store five different types of picture settings for different moods and none of them seemed to remove the graininess of the picture, although a less brighter one did remove the line.For the most part I liked the documentaries on the disc, Back to School and Remembrances. However little mention was made of Dursley McLindon, the actor who played Sergeant Mike Smith throughout the story. Karen Gledhill was really the only one who talked about him, and I wondered why as this stood out a mile during the documentary. I knew he had died very young. I did a search about him on google and yahoo and discovered that he unfortunately had died of an AIDS related illness, I do hope this had nothing to do with the little material used in the documentaries about him as I find bigotry and sweeping under the carpet tactics distasteful. I would've liked a bit more reminiscing about him as a tribute, as his character was integral to the story but either no one asked the other cast members for their thoughts or they didn't want to talk about him or he was simply ignored, I don't know. I can understand if they don't want to point out a cast member died of an aids related illness, in order to preserve the deceased actor's dignity and standing, but to simply ignore their contribution completely is totally unfair and biased, not to mention discriminating and I hold Steve Broster and the interviewing crew responsible for the lack of content about Dursley in this feature.Overall I liked the release, the second disk about Davros was very well made and informative. I liked the CGI elements. I'm giving it a rating of 3 out of 5 simply because their was no tribute to Dursley McLindon. I hope his memory is not tainted by t he lack of any material about him on the release.
