Regarding language and pronunciation.
Some years ago BBC 'English' was crystal clear diction, every vowel pronounced, and everyone understood what was being said.
Then the 'millenials' took over and decided that what was needed was more 'diversity' and regional accents.
Result is now, that without captions on, the chance of understanding what is being said is about zero, and to put the icing on the cake, music was added to give 'atmosphere!!'
