I pretty much like them all except Jack and Harriet who irritate me. Nick,Joel,Sarah,Eileen and Jade are my favourites. Although I think Aaron is good entertainment value
Nick - liked him from Day one. He's savvy but immature & unintentionally funny
Eileen - Cooky, crazy character much required in this rather boring house
Cristian - really didn't like him at the start. Now I think he's adorable & I am looking forward to discovering the real Cristian.
