1) Ryan - He is quite funny and intelligent and doesn't really get much screentime but that's not his fault.
2) Rylan/Razor - They are at least "being themselves" in ways that aren't completely negative and are active and acceptable Big Brother housemates. Both have various flas: Rylan is amazingly self-cenetered and not as amusing as the producers think and Razor is a bit sexist and sratches himself, but I'd take the over the rest.
3) Frankie/Claire/Tricia/Gillian - I'm fine with some housemates being more queit than others. Not everyone can be a "big character" (and big characters are often boohats.) I mean, I have Toadie at number one and he's probably considered "boring" by the mout-breathers on BOTS. But these four are CLEARLY holding back, all too scared to say anything that could be considered controversial in case if ruins their careers. Basically they're scared of turning into Denise Weclh. And that (much like Denise Welch) does not make good viewing. I think this was most perfectly illustrated when Lacey was trying to talk politics but ended up saying a load of crap because her only source for news is probably The Sun and any one of the four of them (well the three women were sitting there at least) could have stepped in and explained how she was factually incorrect or said they disagreed with her opinion or something...but they all just sat there, to scared to say anything, just willing to wait it out and collect their paycheque at the end. Or how about the crying during nominations because they don't want to be seen as saying anything negative (and as MY HERO RYAN proves it's possible to give good nominations without coming across as a boohat) and giving pathetic reasons like "he exercises!" and "she said she was going for a shit!"? Frankie can be highest ranked of the three as I liked the part where he was shooting the other housemates with his toy tank and Gillian can be last because she looks constantly terrified, but really they could all be merged into one housemate.
4) Heidi and Spencer - Just literally horrible people. Being kept in because viewers are so confused now about the whole "we always vote out the good ones!" mistaking any housemate who is featured in the highlights as being "good" just because they're "doing something" and forgetting that part of the fun of Big Brother is actually voting out horrible people.
