I enjoyed reading your post, Chris and I couldn't agree with you more. CBB was hugely entertaining without the need for rich/poor sides or copious amounts of alcohol. The celebrities were also kept busy with lots of tasks which solved the boredom factor.
If BB3 had been the first Big Brother, I certainly wouldn't have tuned in to a second.
I'm prepared to give Channel 4 another chance though so, with fingers crossed, roll on May and BB4.
