I didn't realize that the BBC had started doing promo materials again for the show. Here's one with Patsy Palmer and Maisie Smith.
As for the show, it is HIGHLY plot driven. Though I can see why some see this as a step-up given the years of really poorly executed, regressive, and just boring material. The day to day writing is a bit better and there does seem to more momentum than usual again. There's also a bit more character interaction that we've not really seen much of - the story is trash, but who would have thought Steve McFadden and Jessie Wallace would be sharing so much screentime together? For years, it was said those two hated each other and the show went out of its way to make sure Phil and Kat only shared limited scenes.
Oates and Sen are very much in Santer's vein though - they seem very good at publicity and sensationalist plots, but piss poor at character development. But none of this seems to be paying off in the ratings yet
