It's the OTT twists and feed decrease that has ruined it. If they give us full feed and less OTT twists with better HM selection, that's all they need to do. The nom/eviction format still works worldwide.
I have only enjoyed two twists that C5 have ever done.
BB14 Michael the Puppet.
CBB16, the Triple Bluff (Jarrah going in the secret room with the others knowing).
That's it.
There needs to be 24/7 feed because that is something that will boost voting revenue. More people would become attached to a HM or dislike a HM more if they watch more than an edited show. That's why I love Italian BB and the feed helps the voting numbers.
Regarding that actually, last week there was a record in voting for an eviction, which just proves that public voting still intrigues people if done right. This series of Grande Fratello only averages between 3.0-3.5m, but there was just over 4m votes cast in last weeks eviction between Lidia and Federica (two girls in a sort of love triangle). So more votes than actual viewers.
Federica got into a relationship with Alessandro. Then Lidia, a new arrival (ex of Alessandro) comes in, breaks the relationship and claims she wants him back. He then takes her side over everything. Lidia said "I can't wait until I am up for eviction with her because I will break her in the votes". The HMs on the night were told to stand next to the HM they wanted to stay, when he went and stood next to her, it was the worst boos from the audience I have ever heard.
That's a story that gets eaten up in BB and people love it. And most of the bullying towards Federica (it was her V everyone) wasn't shown on the edits, only the live feed. Well anyway, 4 million votes, and with 75%, Lidia goes (thought it'd be easily 80% to be fair). If all that was shown on the main show, she would have got a Sezer/Nicole %. She wasn't even the worst of them either.
That's why feed is important. We have no idea what we're missing. And if there was feed, people would be more willing to vote as they see a full picture.
