My opinion on all the houseguests:
Annie- She didn't seem that bad, she got into some drama in the first week but I don't think she was that bad to have gone first.. especially being the sabo. and wasting the twist (until it came up again.)
Andrew- He's a mess, didn't like him, still don't, the only thing he did that was memorable is his final speech, where of course he got evicted afterwards.
Brendon- Rachel started out my favorite by JUST a little, with him right behind, and then week 2 Brendon was easily my favorite. He played the best game with Britney one step behind him and he dominated, if he won instead of Hayden (which he was about 2 seconds behind in the HOH he was evicted by), he could have easily made it at least a week further.
Britney- I loved her week 1, also being in my pool of faves with Brendon, Rachel, and Ragan, she has so many gif-worthy and hilarious moments and that's easily one of the many things that made her win America's love and support.
Enzo- Never really liked him, didn't work that hard to get into the final 3 except for making up the idea of the alliance which anyone could have done.. doesn't cut it for me.
Hayden- Never really liked him either but he played a hell of a game, winning tons of HOH's and even 3 in a row, but overall not that worthy of the winner.
Kathy- Also a mess, but not as bad as others, could have at least TRIED in some comps though!
Kristen- A big mess, was a lampshade week 1 to 3, then turned into a busted lightbulb week 4.
Lane- I didn't really like him or care about him until the middle of the game, he's an awesome, hilarious person and of course I feel he should have won against Hayden no matter what.
Matt- A fake, slimy snake.
Monet- Never liked her, how she just sat there and acted like she even wanted to come to the finale made me feel that I will most likely never like her anyway.
Ragan- Equivalent to WAAAmber from season 8.
Started out an awesome, funny person, turned into someone you would puke at whenever you see.
Rachel- The most dramatic person in the house but also the person that you LOVE or LOVE to hate.
