Over the years I've always been frustrated when, as you put it, the most entertaining housemates are booted out.
However, as Terry Christian said, Bea is the first housemate I have ever actually HATED.
And she is not, as a previous comment suggests, a strong woman. Being strong does not equate to deviousness, narcissism, bullying, lying etc etc.
I would find watching her get kicked out this Friday SO satisfying that, no matter what happens during the last week, there will be a permanent smile and glow of satisfaction, in fact, a POSITIVE AURA surrounding me to the extent that I won't care.
She is so awful that I've actually had to change channels a couple of times because I find watching her makes me too angry to feel 'entertained' anymore.
Get the horrible boot out of there.
