I'd say it's definitely failed!
BB has been pretty un-remarkable since C5 have been butchering it but this Series has just been such an all-time low, a total flop!!!!
I've never been less excited about a BB series while it's still running.
There's quite a few reasons but as far as i'm concerned the most notable are;
Apart from 3 or 4 great housemates the rest were awful, awful choices!
Giving someone a pass straight to the final withing 24 hours of them entering the house! Terrible decision, and a blatant and ridiculous manipulation! I have absolutely NO DOUBT that the pass was invented for Helen and there was never a chance of anyone other than her getting the pass! Ridiculous in the extreme!
It's not a new one but this year has been particularly bad for betraying housemates private conversations in the DR or playing back/relaying housemates conversations within the house. Just a cheap way to create drama because they're incapable of creating drama through good production of the show!
And another not new thing but one that's been awful this year is the favouring of certain housemates over others and vice-versa (giving certain housemates negative edits in an attempt to damage their popularity within the house and with the public resulting in them either being nominated or evicted, depending on the timing!).
Incredibly poor and forgettable tasks! Back in the day the Tasks were amazing but since C5 have had the show they just put no effort into them whatsoever! Shameful, really!!!!
There's many more things i could mention but those i've listed have been the real Series Killers for me. If it carries on like this i can see C5 dropping it and i don't know if anyone else will pick it up sadly!
