Consistency doesn't mean loss of production value, even though sometimes a few twists/nomination rules saved some situations. But overall, I think it is better to have a consistent show throughout.
In French BB, at least for the first 6 series, one week only males were put for nomination, the other week only females etc... That gave the show consistency and the public knew what was going to happen beforehand. But they went the same way as C5, making it a mess and having it cancelled since this year.
