It just refreshes the series and adds a new dimension to it. No idea why people on this forum seem to be against it, its been a tradition in the golden years of Big Brother. Used to be so exciting seeing new faces come out of the car (idk the car just made everything seem so exciting

) and surprise the housemates
Ideally, I'd like 3 new housemates in week 3 and 2 housemates in week 6
