BB15 had no gems whatsoever besides Judd. That's why it sucks worse than BB16. And of course, BB9 is way worse aswell.
Bb15 has Derrick (insane mastermind), Donny, Zach, and Nicole as clear all stars.
And we don't have someone who's actually dominated the game in the final five instead of someone who floated back and forth until he got shit fucking lucky.
