Yeah, Selfridge does alright and is safe, for now.
The first two (back to back) episodes did disappoint me. I complain that Downton should be soapier, but on Selfridge you could feel the soapy plots being forced into place--when Mr Lovewhashisname came on, he really should have been twirling his mustache (the fact that ANYONE would trust that character the way he acts is ridiculous.) Still, I like some of the side characters, so... And couldn't they make Sergei a LITTLE more likeable? It's hard to get invested when we've never seen why the daughter (Violet?) would care for him in the first place. Even a scene or two of them would help. Agreed on Zoe Wannamaker, though--I was pretty leased to see her pop up.
(And the daughters being suddenly SO front and center seemed a bit forced.)
Re WWI, after the premier they had a preview of upcoming UK imports on Masterpiece--the ones I knew about (Wolf Hall, the Poldark reboot,) but there's one about nurses in WWI. Which is why I was thinking it seemed a common theme right now (yes, I know it was recently the anniversary, etc.)
I suspect The Gilded Age--if it even gets picked up, will suffer the fate of the US Upstairs Downstairs--Beacon Hill. That did apparently start with huge ratings that disappeared overnight. People don't seem to realize that a large part of the appeal of these period soaps for Americans *IS* that they're British.
Besides apparently doing a 2013 treatment for the Babs Gypsy (which rumour says someone else is writing now,) Julian has NO major credits that are about anyone but Brits-- Can the Baron Fellowes of West Stafford write American historical drama?
