I’ve not watched them all yet but about 7. The third one with Harriet Walter is my favourite just about. Also the one I’ve found the most tragic, though all are sad. But it’s a close thing with the first three Imelda Staunton, Sarah Lancashire (I think that was new , there were some modern references and the sets looked More 21st century. I was under the impression a few are ?) then Harriet Walter. And the fourth with Jodie comer very very close to. Funny that the male actors haven’t been quite as exceptional so far. Or maybe it’s the monologues themselves. I’ve also watched Kristin Scott Thomas’s though, which was enjoyable but also not on the same level. Story wise or acting wise. Overall tho it’s probably some of the best stuff I’ve ever watched, honestly.
