Thanks for the responses, some obvious ones I forgot. Especially Caroline, who now I think about it, was my launch night favourite too.
I always find it a shame about Shievonne, she was definitely one of the best housemates (for me) until she got all grumpy and confrontational. Even when she did, I really wanted her to pull it back. Regardless of how she started to annoy people though, her going against Conor was ridiculous.
As for Toya, I always thought she was popular at first (though that could have just been a forum thing I guess). Though even if she wasn't popular with the bookies, I remember her being cheered going in and certainly didn't have her down as a Week 3 eviction. She was like some others mentioned, seemed really bubbly and entertaining at first and then got grumpy and angry most of the time (but she definitely won me back around in her final week when she took on Team Twat).
