While I do still think most of the series 1 episodes after The End are probably the best we will ever see them i.e. a fair improvement (series 1 is the oldest recorded anyway), I have to agree with you that series 2 is a more substantial step forward in image quality. The colours are much more vivid and appealing to the eye while it is virtually all much sharper. Anyone doubting the quality of this Blu-ray box set's picture should surely not criticise how the late 1988 run has turned out. However, while I enjoyed the image even more than series 1, I am really dreading what it will look like in just after five more episodes time. If it can be rectified, replacement discs issued please.
