So out of curiousity, do you enjoy BBAU or BBUS better? BBUS is, essentially, what you said it's meant to be. No additional storylines, no outside interference, 24/7 live feeds and no ridiculous tasks other than the HOH, Have/Have Not, & PoV competitions. However, most Americans that have seen both, prefer BBAU to BBUS.
I am Kiwi, so I'm not too bias to either US or Aus. I watched US version season 8 which was really cool (if you want to watch one, watch that one) but the USBB is way way more produced than AusBB- they do that typical US reality thing where they interview them to explain all the events so they can cut the interviews over top of the action and they end up commentating themselves (example here, and happens through the entire video).
It is like the producers are making it for really really dumb people who can't figure out what is happening unless it is being explained in absolute detail from the perspective of everyone involved. It gets tedious.
Australia feels much more organic and the viewers can come up with their own idea of what is happening without the producers treating them like fuckin kids - though channel 9 has cranked the production up which is a real shame.
