Finally got around to watching this and all I can say is WOW!
Not perfect, but mostly excellent. I agree tho' that Pine's motivation is a bit too neat and convenient. And yes, the whole series did remind me of LTK. The River House intrigue goes on a bit in episodes 4 and 5. Almost entirely outstanding performances, in particular Laurie, Hollander and Debicki. I wasn't as taken with Olivia Colman as some of you. Too matronly and at times maudlin, though some of her dialogue doesn't help.
And yep, this felt like a movie, not at all like tv. I'm really let down that Bier won't be directing B25. She's exactly what the film series needs.
