I really enjoyed it - bonkers but very fun and thrilling.
I am definitely Team Paula for the moment! Started to warm to Ellen when she started to cackle away to her baby though - I dread to think what that says about me.
I think the problem with liking Ellen that much is Morven Christie isn't as good an actress as Vicky McClure. She started to annoy me too on S3 of Line of Duty, but she seems to be relishing playing villainous, so it's fun to watch her grappling at Ellen's bump and undermining her. Also, Morven Christie played Ellen as so tight lipped and smug in the beginning (ditto Dougray Scott being so creepy and touchy-feely) that I sort of hoped Paula would win.
I did think that it was slightly hampered - at least in the plausibility/feeling-for-Ellen stakes - by being just an hour, because it all happened so quickly and Ellen seemed to be overreacting and snapping at every last thing. Being gaslit like that though is my worst nightmare. Also, it doesn't help that Morven Christie looks super young to be such a high-ranking architect with such a good career, so her husband being a qualified psychiatrist who also treated her seemed a little ????
My bold prediction right now is similar to above: I reckon Ellen's husband is the villain. He knows she feels threatened by Paula so he's been playing them off one another - how did she get his number? - by telling Ellen to 'accept' her and creating more conflict between Paula and Ellen because he knows she'll do something to annoy Ellen. He doesn't want Ellen to be a career woman and hopes to scare her away from ever going back to work and being a meek housewife. He was suspiciously nowhere to be seen when Kay died, and he even has the Norma Bates style psychiatrist mother! IMO, he's already a villain by sleeping with a vulnerable patient (isn't that illegal?) after her mother died.
I'm hoping Paula is the villain though, so she can unleash her full Fatal Attraction craziness. Paula is creepy anyway, and so is her husband.
