I know Alice wasn't particularly interesting, but there weren't really any other housemates towards the end of BB08 that I found likeable enough for me to want to support them.
Ben came across as a bit of a snake to me on a few different occasions. He was more than happy to go along with Nobbi, Rory and the rest of the spa mafia boys club when they were tiring to annoy someone, but then tried to play the innocent whenever it blew up into a major drama. Ben was a willing collaborator in Nobbi's attempts to create friction between Alice and Travis, but when it caused a big argument, he then tried to distance himself from it and pin it all on Nobbi.
Bianca was good for a bit of drama, but most of what I can remember about her involves her screaming at people and getting into arguments (Cory, Alice and Renae, Rima etc). I'm struggling to remember other things about her.
I couldn't stand Rory though. The guy just came across like a complete pig. I agree with Will about Bridgette being entertaining. I wouldn't have minded her winning.
