I'm enjoying Sonia more and more as the weeks go by. She's still a bit awkward, but she's doing a great job. She engages with the housemates well and looks comfortable improvising. She looks great for her age, and if she's had surgery done, she's one of the few who actually get it done right.
She was a contender for hosting the show from the start, and from what I've seen so far she was the right host for the job. I can't think of any other personality who could do a better job (other than Gretel of course, but that's never going to happen again), she's got the sort of personality that makes her fit well as host of BB.
For the Love of God though, give her a couch to sit on during the evictions. Part of her awkwardness stems from the fact that she's standing on the stage for the entirety of the show. I also wonder why nominations appear to be held in the auditorium and not a smaller studio this year? The nominations show just doesn't seem the type of show that deserves the spectacle of the auditorium.
