This week's episodes have been completely ruined for my wife and I who have watched the series for a number of years even viewing episodes to watch later. For some reason ot has been decided to drown out much of the conversation with a background noise I can't even call it music, therefore we miss most of the information. Also as we wear hearing aids the fact that channel 4 has for whatever reason stopped using sub titles has again meant that we cannot even use that facility to assist us in our viewing. Please can this be looked into and at least stop the awful noise "music?" That has been suddenly introduced. A once very enjoyable programme is now a trial to watch and will certainly lead to our stopping watching.
