I felt exactly the same last year though. I missed Caggy, Anna, Tom et al and even Marjory.
I never thought in the first week that I'd get to like the new housemates, but I can safely say that I preferred BB2 to BB1 in the end.
So stick with it, I'm sure once a few people go and the ones left are able to show their real selfs a bit we'll love them too.
Oh, and by the way, I LOVE the split house idea, it's eeevill
