The lead actors are serious actors. But Jonny, seems to my aging ears, mutters a lot, buries his words in his head voice, and not all his dialogue is easy to hear. I wonder if that is part of the recording process and I sometimes have that problem with Lucy as well on this program.Then to make it worse, even in early segments, there is unrelated music in the background adding nothing dramatically, but compounding the muttering problem. CBS seems to add this music on other shows as well while other broadcasters do not, to their benefit. Since much of the drama of the show is Jonny Lee/Sherlock's thought process, and that is at the heart of the character's intrigue, this loss of vocal clarity is self-destructive. I wonder what others think.
