They never quite 'bounce back' I find, when a main character leaves,<quoted text>
I am finding that Downton has lost its edge with this series and is the worse for the departure of Dan Stevens (Matthew). I feel that Julian Fellowes is running out of ideas and now recycling old ones - which is never good for the survival of a series. I had huge admiration for John Cleese and Connie Booth with Fawlty Towers - two series , each of 6 programmes, and then called it a day and stuck to that, despite financial inducements.
and I agree, recycling old ideas just does not work. Also the failing,
for myself anyway, of Dallas. Good point about Fawlty Towers Tony.
