I'm not one who says that someone who has won before can't win again, but...
in this case the playing field wasn't exactly level from the start.
When individuals that have been through the BB experience before (the stress of the game along with the mental fatigue of being cut off from the outside world and your loved ones) are pitted against virgins (who think they know what they are getting into, but can't really), there is already a disparity. I think rational people would have to agree with that.
It's especially uneven considering that this group of previous players had all either won or at least all gone deep into the game before. So they were all well versed at the winning strategies of the game (Britney less than the others) and bring that knowledge to play against people who have only seen the action play out on TV before, if even that.
Also, they took those returnees and gave them 'coaching' positions. So the newbies who are already slightly in awe of their new celeb housemates immediately are in a situation where they look up to the coaches for guidance. This served to minimize any sense the smartest or less star-struck newbies would have had of recognizing the threat of the vets and thoughts of getting them out with a quickness...when the eventuality arrived that their coaches would become their competitors.
And I'd say it's further inherently unfair for those returnees to play under protected status for the first month (or month and a half or whatever it was). And that fact would be an even bigger deal to me if I were a player in the game.
But all that being said, if the remaining newbies don't unite to get rid of the veterans when they are able, then they look stupid for ultimately losing to one of them - if that's how it plays out.
So it's not necessarily unfair for a player to have a repeat win, but there is quite about bit that is uneven about this season.
Although Dan has done some solid manipulating, the majority of it (and the moves that saved his ass and people seem in awe of) has happened since the other vets were all voted out. If Dan had done that funeral bullshit while either Janelle or Boogie were still there...wouldn't have worked at all. They would have laughed at that show he put on. Actually, he might not have even tried it.
So I'm less impressed by the work he's done of late than I would be if it were against players who'd been there before.
....and I can't believe I just wrote that much about this stupid show....sorry about the long post.
