IMO she is not "shady and manipulative" so much as she is just way better than the others at pretending she doesn't give a hoot about them or their various conflicts. ("Why would I be upset? Who cares? I don't know what you're so upset about" etc.) That's always annoying during a conflict and the one who does it better usually wins 😄
I enjoy actual British humor, tv shows, etc. My problem with LVP (and now PeeKayy) is that they just aren't that humorous. I tend to think of British humor as having wit or cleverness and I find that lacking in most of her "jokes". (Maloof hoof was cute - I'll give her that, but even a blind squirrel finds a nut occasionally) I've only just started watching VDP Rules after catching it on a flight last year, but I already can't count the number of "balls" and "nuts" jokes she's made to her male staff. And you can tell they're just laughing out of obligation and trying to get on with the conversation. My former 7th grade students would have found her hilarious, but I'm about her age and just find it annoying.
An example from this season - she's acting like she could care less about Dorit's dog dumping, but then accepts Dorit's invitation to the Bahamas, gets on the plane, and acts put out that Dorit wants to share the big suite with her because she snores too much. A jab at Dorit? Yes. Hurt Dorit's feelings? I think so. LVP's own special way of showing that she actually is pissed at Dorit? Absolutely. Funny? If the idea that someone snores makes you laugh, I guess. But witty or clever? Not in my opinion.
