Yes, I will miss it. As much as this current format is pre-recorded, highly edited and storyline-scripted, I still do enjoy watching it. Any BB is better than no BB.
That said, I still think the original format was by far the best. Everything the people have said in this forum thread is spot on ... without the ability to get to know the HMs by seeing their conversations, without live feeds, without shows like "Up Late", etc, there is absolutely no viewer "engagement" with the show. That was what made it popular. Viewers could form opinions about HMs and debates would take place in schools and work-places about which HM was good/bad/best/worst. It would make the papers, magazines and the even the nighly news. Not to mention the "drama" and "edge-of-your-seat" stuff at the end of week eviction show when the viewers and the HMs had no idea who was going to be evicted. None of that happens with this pre-recorded stuff. With the pre-recorded stuff, we even know who is going to get evicted before they even air the show (eg, Drew and the Tully advertising promos made it obvious that Drew wasn't going to be evicted).
I think the problem with bringing back the old format is the networks "fear of liability". Fear of having another "Turkey Slap" type of incident is what scares them away. Considering the "F" word now graces our TV screens like it is just another everyday normal word, I cannot understand their fear. I see no reason why they can't just put warnings up before the show ... "This show may contain blah blah blah. Viewer discretion is advised" ... and then have a delay like they do on radio which provides the producers/BB with the ability to stop and/or handle a "not-screen-worthy" situation which may be developing or occuring in the house. Heck, it could even be a 30 minute delay. Sure, it wouldn't be live with such a delay, but, a delay (even a 30 minute one) is better than it being pre-recorded and edited. Throw it on in a slightly later time slot (so kids are in bed), and away we go. If they bring back the viewer engagement, and enhance that even more from what it used to be by using Twitter and other modern-day technologies, then the ratings should, surely, pick up. And, as someone else has mentioned, if they go down this kind of path again, then they could once again use BB as a means to make some money (as much as I personally hate having to pay subscriptions – but from a network executive point of view, it's a winner).
Yes, I will certainly miss BB if it gets cancelled. And, despite it's flaws, yes, even this pre-recorded version.
