i completely agree. BB has gone totally softcock. it's bad enough the rules aren't enforced and that the HMs are basically on a holiday with the weak challenges and frequent perks. but there's hardly any conflict in the challenges - the least/most challenge is the first in a long time to have even a smidgen of that (tim's ice cream dilemma is probably the last one, that's how long it's been)
the sad fact, though, is that there are two forces working together to suck the life out of big brother
force 1) channel 9. they insist on this family friendly angle and believe that the only formula for a winning show for this target is home & away
force 2) endemol/southern star. they are producing the show from a "cost control" first priority. it's far too expensive to track all the hosuemates all day (and construct narratives from the hundreds of hours of footage that would produce), so it's far easier (and, more importantly, cheaper!) to produce the show from "set pieces". These are the manufactured events that are almost all of what we see on the big brother shows today.
combine these two forces, and you have southern star producing childish set pieces of little interest or challenge. and if those interesting or challenging things happen in the house, they'll be neutered for air to ensure that channel 9 doesn't get their knickers in a twist.
at the end of the day, we're left with a show that is a shadow of its former self - storylines driven by edits to fit pre-conceived caricatures and narratives that are meant to appeal to the home & away crowd.
thankfully, we have BBB so that we can drown our sorrows together
edit: and let me add that there's actually a kernal of greatness that this intersection has made - this is easily the best cast they've had, perhaps ever, and if we were given a glimpse of their individuality, depth and many-faceted relationships with each other... well, that's just a dream, isn't it
