People just don't like great alliances, especially when they just don't like their personalities which is fair I guess. Still doesn't change that the Detonators are playing it smart (Derrick & Cody mainly) and are taking out literally every one of their main competition one by one. Partly because these houseguests don't know what they're doing but also because they keep making good decisions and getting in the right peoples' heads. That's great BB gameplay, and they're staying off the radar pretty well for as much as they've been able to do to benefit their games.
Every alliance isn't going to fall apart within the first couple weeks of forming. There's going to be successes like the Brigade and so far the Detonators, or more so the Hitmen. Doesn't make it boring, there's still enough going on where the show isn't bad at all. I like to see seasons like these.
