Firstly, the Good: Well this is a classic series, which is just great, the picture and sound is good, but as I will mention soon, the picture is not good enough, the price from Zavvi, is very good when I purched them, and delivery was excellent. A lot of people have commented about the cropping of the picture in 16:9, this to us, is not too noticeable, and is better than the black lines either side. The bad: Even though these are in HD, there is a lot of grain present at times in the picture, which to us is not acceptable, now we have very old films that Disney have done on blu ray, dating from the 1940's. and the picture qaulity on these, we cannot fault in HD Blu ray, if Disney, and other companies can do this, then ITV could have done it with these. We pay good money for great looking HD picture, not to have a lot of sandy grain, on our screen at times, so hence, only 3 stars. We do own the dvd's as well, and yes, the Blu ray's are better, but could be a lot better.
