Season 14 - Frank & Kara
Frank was the target for this entire season and given another chance, could win a season. Kara was another victim of something she couldn't control, this time a "Screw Dan" alliance. Let her have a chance to actually play.
I very much agree with the rest of your list, but not Frank and Kara. Kara was just boring as hell, had no personality on feeds or in DR. And I hated Frank with a passion, he was so arrogant, immature, and cocky. His week of pouting with Boogie really put me over the edge. Can't stand this guy. I don't think much of the BB14 cast was that great, but I guess I would have to choose Wil (for pure entertainment) and of course Jodi, who never had a chance!
