1) BB5 - it was fresh, dramatic, funny, had a great line up, first to feature truly interesting tasks

2) BB3 - made BB bigger than it was in BB1 and 2 with more housemates, a new and bigger house, first week eviction, rich/poor divide, introduced live tasks. Really upped the ante.

3) Overrated BB7 - the first 5 weeks were awesome but the lineup wasn't great, and the long-awaited second house twist kinda failed because the 5 new HMs didn't really add much and if anything helped slow the series down as it seemed like we were back to square one all over again. The prison task was good but generally the tasks sucked comapred to BB5 and 6
