I'm like you Mandy, I do tend to get addicted to all sorts of "tv programmes" that other people would probably, quite understandably, dismiss as trash. I think, oh, I'll just see what the house mates are like, complain about them all, and then continue to watch it avidly.
However I totally agree with what you say Lins that increasingly there are vulnerable people in the house who probably shouldn't be there and certainly shouldn't be there as "entertainment".
I also think contestants are getting wise to what works in the house. Allegedly Brian's (last year's winner) mum said he wasn't like the person shown on the programme but had recorded all the previous series' and worked out what worked best in winning over the viewers.
I'm sure there are a few people who we could put in the Big Brother house and watch them squirm if we were being really awful (cue dracula style laugh) any suggestions??
