I think it'd be good if there was some kind of task early on that twisted the whole series - I was thinking a housemate would pick a number, e.g. 3, and every 3rd week the nominations would get flipped on their heads, so the housemates with the least nominations every 3rd week would be up for eviction, but BB wouldn't tell the housemates that, so they'd get paranoid. Or, they could tell the housemates that, and then they'd start voting extremely tactically, and it wouldn't be beyond BB to then twist it again.

But I don't like twists that last for a few days and then are over - they're publicity stunts.
