In my personal opinions...
The most recent one- 21 - Abbie & Ryan. Can't believe how I hated them at first...
15 - Eric & Lisa, that 'twist' was probably one of the biggest mistake TAR have ever done, especially they looked like a strong team that could have gone far.
Amanda & Kris - on both seasons. Imagine how far they would've gone if those (both) U-Turns didn't exist.
12 - Nate & Jen. Their elimination was just simply so sad for me. I always hate bickering couples but they're one of my exceptions!
10 - Dustin & Kandice. Their interview after their elimination was so heartbreaking..Is it just me or Phil kinda sighed when he saw D/K running up the stairs, when he was about to eliminate them?
9 - MoJo - The only likable team out of the F4 in my opinion.
5 - Bowling Moms - Even if they wouldn't have won, they would have made a WAY better history as the first F/F team to enter the F3 instead of Lyn & Karlyn. And Charla & Mirna!
That's all I can think now. Even though I know there are more sadder eliminations than those!
