livin4reality - CBS can sue, but ABC can also say that they might want to go and sue the BBC who actually created the "big brother" franchise to begin with. CBS is treading thin ice there - the employee issue however can possibly be challenged.
As far as this season on Big Brother - how about an actual slice of REAL America, not hot bodies that look great in bikinis (including hot seniors), not actor/actress wannabes, and not people who are there just for drama.
And most DEFINITELY NOT more old houseguests coming for a second chance. Leave it for an All-Star season or - heaven forbid - a winter season when most of us won't be watching anyway as there will be another writer's strike probably if that's happening.
We want more nerdy (but pleasant - i.e. NOT Colton of "Survivor" nerdy) types, we want more Remmy or Jerry types (older even if crumudgeonly), we want to actually HAVE FUN watching the show and the live feeds.
