'Mercy Street' is NOT the replacement for 'Downton Abbey' I don't...
know why there are some people saying that! In order for it to BE the replacement series for 'Downton Abbey' (applies to all series) it has to be shown in the same time-slot. This is shown in the time-slot after the one that 'Downtown Abbey' is. I don't recall which series 'Mercy Street' has replaced. Also 'Downton Abbey' has not have its series-finale yet. Once it has then the following Sunday will be the replacement series for 'Downtown Abbey'. Same for 'Merry Street'.
I'll let you know when I come-up with a new signature, .
