I didn't watch series two but have seen clips, and it reminds me a bit of Channel 4 era Big Brother. A bit of conflict (provided it didn't get out of hand like fight night in BB5)would be good, I know there was a fight in Love Island Australia last year. But out version is now very sanitised it probably wouldn't ever be shown.
I work in a school and I know most of our year six girls are obsessed with it, so kids ARE watching it.
