This series was billed as BB 'gets evil' (or something similar), withthe management playing 'tricks' on the inmayes (or so I gather).
As the average volunteer for this show is a narccissist(sp?), just trying to get some minor fame, might I suggest a series where BB gets 'Really Evil':
Put the housemates in the building, run them through the hoops, BUT DON'T BROADCAST LIVE (just a single one or two hour show of the hogh/low lights shown at some ungodly hour of the morning at the end of the run) - evictiond by random selection from the nominees.
