The celebrity version was meant to be a light hearted, shortened and a bit of fun for viewers and HMs alike, though it had its darker side for some of them. There is still validity in that if they stop importing idiotic vapid Americans with inflated chests, radioactive teeth and egos that would sink battleships, with the sole remit to be destructive.
The normal BB should revert to the serious version with very strict rules, no outside contact, full live feed , HMs without agents or media experience and bring back follow on programmes like "diary room uncut" and a proper type of "Bots" with good analytical discussion, no freaky guests on the panel or audience, and definitely NO Rylan flaming Clark or what ever he is called.
Then it might be watchable. The trivial trash approach is killing it. Or has killed it.
