I guess if everyone involved profited and it rated consistently and reasonably  well (which it did for the most part in targeted demographics, I believe) then there's no reason it won't be back, is there?  Or is that just wishful thinking on my part?
If it does come back, I just hope more thought is truly given to what the original concept of this show is about.     2014 BB was a sad and pathetic shell of its former self.  It lacked spontaneity which is the life-blood of a social experiment such as this.  Stop the micro-managing, control-freak mentality and let it breathe.  Dump the contrived/staged elements and the manipulation through editing that was so nauseously rampant this season.  It's an insult to our intelligence and precludes us making a true connection to the Housemates. So many times in these forums, people have stated that they don't know these HM's.  It was being said as late as last week so that surely rings alarm bells?   We kept hearing various things from evicted HM's and were left scratching our heads in wonderment because we weren't being shown what they talked about.  It's dishonest and not in keeping with the spirit of this concept.  That's why, if it does return, it's imperative to include live feeds and at least one show with  an adults only theme.
The programming/air-time must also improve...what a debacle it was this year.  Chaotic, inconsistent and so frustrating that even avid fans had trouble keeping up at times.
Ooops...turning into a novel...I'll stop rambling now.
