Any die-hard Big Brother fan can see, plain and clear, that this season is a flop. From my perspective, the main reason for BB16's failure is production tampering with the game.
All of the twists this season did not make the show more exciting. They actually had the opposite effect: they made the show more predictable. The fact that the HoH could not retain their safety for the week, and the fact that FIVE houseguests could be nominated (including a replacement nom after PoV), meant no one had the confidence to make "big" moves. Makes sense, because that would be potentially four houseguests coming after the HoH with a vengeance the following week! I wouldn't want to make big moves either if that were the case!
So of course, Victoria, Jocasta and the likes got nominated time and time again. Donny said it best when he nominated Victoria for eviction: "your blood is on everybody's hands and now it diluted onto mine". What makes people confident to make bold moves on Big Brother is the degree of certainty in knowing that what they want to happen, will happen. That degree decreased a ton with this twist. It's no surprise, then, that the only ounce of excitement we got was on Double Eviction night where Hayden was blindsided. The chances of him leaving were greater, so they had more confidence that they could pull it off.
The two HoH/Battle of Block twist also made it easy for the women to become targets. They didn't feel safe with one another because of the uncertainty of it all, and were not able to ban together, making them very easy targets for the men to pick off. Show any signs of dissent or even express the desire the make a "big move" and you're a goner. That's exactly what happened to both Brittany and Amber.
Another reason why this season is a flop is because of the bad casting. The problem is because the vast majority of the houseguests are unfamiliar with the game. The only applicants who were familiar with the show prior to being cast were Donny, Christine, Derrick, Frankie, Jocasta, Nicole and Zach, which means over 50% of the houseguests were recruits/applied knowing nothing about the show. It looks as though CBS is more concerned with having a good-looking cast rather than one willing to play hard. Because seriously, how many alpha males and models do we need?
In the end, while I do think this specific batch of houseguests were weak-minded and bland, I blame the majority of the predictability of the season on the stupid twist. I have to suggest that for the next season of Big Brother, they cut it out with the twists all together. Bring it back to basics. No advantages, no Team America, just regular old Big Brother. And as for casting, they should take a look at both BBCan2 and Survivor 28 for tips. Both of those seasons were chock full of strong-willed players, willing to do anything to make it to the end. Enough with the recruits, I say! Or, if they really want to give us BB fans a nice palate cleanser, just bring on All-Stars 2 already!
