No, it is not. Although the actors are playing themselves, they are following a script. I've heard that they might have been improvising at some points as well so I can't tell how close the characters are to the real actors. Rose and a few other inhabitants of the house are characters created for this show.
I usually don't comment on reviews but I just had to let you know how much I cracked up while reading what you said about the wig. I was thinking the exact same thing. I wouldn't be surprised at all if it is the one Ja had in UWMA.
I love your review. It makes me want to watch the show again.
