I think that Big Mother needs to stay. Many people see her as part of Big Brother. I personally wouldn't like it if she were replaced with a new presenter and several people I know who
don't even like Big Brother agree with me about this.
Emma from BBLB? She might be a good presenter but I really think she needs to commit to the show like Davina to EVER be able to fill her role. And personally I think she is the only one who could possible replaced Davina and only because, she is in many ways, sort of a younger version of her.
Also I do think BBUK needs to take some ideas from foreign editions. I have always said/thought that the HoH (Head of House/Household) would be an amazing addition to the show if it were implemented properly. Not the crappy half-assed version form BB9, but more like the American version, where the HoH has their own bedroom etc. Vote to Save is also another vital thing that needs to be brought in.
Well thats what I think lol
