I wouldn't mind if it was just odd bits - but often it is enough to make me switch off because I have no idea what is going on. The series a while back of SS-GB (or was it GB-SS, can't remember) I gave up on after the first episode - there was a major female character and I literally never understood a single word she mumbled. 'Jamaica Inn' - which Veronica had so looked forward to - it was one of her favourite books - was just as bad. There were so many complaints about the music swamping the dialogue that episode two was a bit better and Veronica preserved, but I just gave up and went into the other room and read whilst it was on.
