If this was a Bansky stunt to get me annoyed, then it worked. Of all these people with all this money and fame who can buy all the education and information in the world, Percy was the only one who had anything interesting to say, whether or not you agree with what he's saying. Collin's taste is horrible, aside from the picturesque exterior, her home looks like a funeral home and she looks like she's desperate to be sixteen again. Her daughter seems nice but another bore. Tamara came off as shallow and the gay guy does more disservice to his gay race by acting stupid and bossy at the dinner table. The comedian was there just as a working gig, so there you have it. No self respecting cook would wipe the table with a broom she just used on the floor, or wear her hair so long under her hat. The costumes were flamboyant and incredible.
I can't imagine that Bansky would sell off his lucrative mystique to try out a dinner party "just for once" with a group of people he can already predict. Most likely they are all acting for Bansky's PR company and they've all signed contracts to keep their traps shut.
