For me so far Bea is not the most hated, I don't like what she did to Freddie and other things that she does, but sometimes she also shows an interesting side which I haven't seen in many other people...
Like I can't remember the name of that girl who was the girlfriend of one cook in BB last year.
In her there was only one side and I didn't see anything positive on her, I just turned off the TV

i feel shes a big biatch but ..there have been women in there as equally biatchy ie grace, nicole ..
