The shown has gotten old. Perhaps they ought to go back to more of the earlier seasons and ditch the stupid twists and revolving front door. A new house would be refreshing too. It's nice spending other people's money but I'm sure CBS can lay out some money. They could always sell the current house to Adam since he thinks it should be a shrine in memory of his greatness.
What if they changed the HoH from a competition to a house vote with American voting as well. The top vote getter from America gets a vote from Julie. I guess the downside is a strong alliance could rule the house indefinitely.
I suppose the other interesting twist is bring it back to season 1, instead of the HoH picking the 2 block nominees, the HGs pick the 2 block nominees. To keep the HoH still relevant give them the power to also veto a nomination (in addition to PoV) and perhaps the first couple of weeks the HoH gets immunity of being nominated the following week. I think that could be interesting if 1 faction wins HoH and another wins PoV.
I don't know, just throwing things out there...
