Hi Vlad,
I really love Clarice's work as Minerva Trask, too! It's quite subtle but she really made her a very different characterization than Abigail... the first time I watched the shows, I remember thinking, "Oh, she's doing the Abigail shtick again," but the character of Minerva is really very different.
There's this wonderful scene where Minerva and Laura bond around their views on child-rearing. That scene always has me in stitches. Both ladies are clearly very complacent in their views... a wonderful example of bizarre, understated, classic DS humor!
Best, Steve
