No messing with nominations to save the producers faves. If people break the rules, punish them in ways other than to 'put everyone they dislike up for eviction'
No more boring dolly girl/pretty boy types who offer nothing buy eye candy.
Less interfering by BB. This includes during fights/arguments. People fight all the time in real life, its not going to shock the audience too much to see someone punch someone else is it? And offcom...well who cares. What will they do? Last show and all.
I will think of more, these are off the top of my head..
