I don't like housemates who have been on the outside for a bit.... I'm not really talking about newbies, I mean housemates who were evicted and re-entered. Simon even fits into this category. They meet the housemates and interact with them, this all forms an instant opinion then they leave and watch the show, other media or are influenced by others opinions so they are far more tactical on re-entry and more media savvy to how they are perceived.
Any housemate who has ever gone back in is completely different to how they were originally.
Going by how the 4 out crowd have been going on in BOTS then I wouldn't want any of them going back in and I quite liked Sarah in the house.
Regardless of if their evictions were fair or not I don't ever want a housemate re-entry again. I was a huge fan of Nikki and although I still liked her after she went back she was a completely different housemate and a lot of what she did was put on because she knew what the public were looking for in her.
