There's a dozen threads on why the Divas suck right now, but the biggest to me: there are no characters. Jillian is a singer, and that's about it. At least on Raw that is.
And what's funny about that is she's the only one who gets a good reaction consistently. The fans always moan when they see her, because they HATE the character she plays.
There are so many awesome things you can do with women in pro wrestling. Jillian is a great example of that, and so is Mickie's old character when she first joined. Why WWE refuses to make these women complex ... I'll never know.
I guess they just want things to be as simple as possible with the audience they're targeting.
