As far as BB's place in the pantheon of great TV shows - it's hard to say without seeing whether they stick the landing, but I will say this: there has been no show - EVER - that has had me as riveting to the edge of my seat as BB. I don't think I took a breath during the last five minutes Sunday night, and it's not the first time this show has had that effect on me.
