Why fix something that's broke. Everybody in the US is satisfied with the format right now because look at Season 1. Mega, Jordan, and Brittany gone in the first four weeks. And the ratings plumided so badly they weren't going to do a Big Brother 2. The ratings suffered until BB3 where it finally regained an audience. As for secret missions, I think that it would be fun to see secret missions and such on the show between contestants. However enough with Different Powers, we had the Coup De'Tat this last season and it failed miserably. POV and HoH are enough. We're not getting a daily show anymore because quite frankly, nobody would watch it. It's better in a perfect little edited package 3 days a week. I will agree with you that this series over here may not be as crazy and exciting, but its still majorly entertaining with and without the strategy and backstabbing between contestants. As for too many nice people? Ummm no, definitly not.
We've had:
Chilltown (Dr. Will and Mike Boogie)
A Black Supremesist who Hates Whites and Jews (Will Mega)
A Paraplygic Who Hated Everyone in the House (Eddie McGee)
The Four Horsemen of Season 5 (Jase and Scott mostly)
The Friendship of Season 6 (April, Beau, Ivette, Maggie, Jennifer, Cappy)
Alison and Jun from Season 4, who ended up being the Final 2
James from Seasons 6 & 7
If anything we have too many evil people in the house....I take that back you can never have enough evil people in the BB House
, but the point is all the contestants are FAR from nice. I'm guessing you only started watching US BB during the All-Stars edition, if so you missed out on pivot seasons 1, 2, 5, 6
