Good topic idea Mike
I think from a viewers point of view, it has its disadvantages and advantages. Advantages are that its good to watch as the groups form and to see them bitch about each other and to see which housemates sit on the fence. Disadvantages are that it makes the nominations & eviction far too predictable. Back in BB3/BB4 it was a lot harder to call who would be nominated, and sometimes to tell who would be evicted. But now most people can correctly predict who will b evicted before the nominations are announced.
