I have never seen it before now, I watched the opening 2 programmes and it was sooo different from UK BB its more like watching a scripted series, all the reality seems to be squeezed from it.
Also the couples twist really put me off, because you may like one person who turns out to be with someone who goes and you have no indication who this could be as there is no lead up.
The show just seems to skip from scene to scene, it makes no sense and its boring. There is nothing for the watcher to work out for themselves, not a lot of guessing involved.
In the UK BB the each watcher can possibly see the same programme very differently and get different things from it depending on their perspective, all of that flexibility seems to have been rinsed from USA BB.
As you may be able to tell I am not impressed! Saying that I did watch the catch up 3 shows at the weekend, thereby negating all of the above I suppose!!
