Because it's ****ing horrendous these days perhaps ?
Channel 4 were getting progressively worse with each series towards the end and now Channel 5 has just smashed the arse out of it completely.

The whole premise of Big Brother was that Big Brother was in total control but they just let them do what the **** they want now with no rules or punishments whatsoever.
On top of that the tasks and general production values of the show are appaling too. There's just very little to keep people interested and watching any more!
