As in when this housemate got evicted, the flow of the series changed drastically whether for the better or the worse.

BB2- Narinder. After her eviction the rest of the series revolved around only one prominent storyline (Paul and Helen), besides that BB2 after her eviction is generally a snoozefest.

BB4- Anosuka. Like what I have mentioned before if she had survived the first week eviction, she would have gone very far. She made that first week of BB4 and if she stayed then the series would have been much more tolerable to watch. Also she would have kept us entertained before Lisa came in.

BB7- Nikki's original eviction. I know that the likes of Sezer and Grace getting evicted impacted the series as well, Nikki's eviction sealed the fact that only certain housmates made BB7 a great series. From her original eviction to the time she got back Aisleyne and to an extent Susie, carried that series on their backs.

BB8- Charley. Her leaving on Week 8 made an entertaining series become a chore to watch. This is probably the biggest change of any of the series because after her eviction, the only constant storyline was Chiggy. But then obviously that didn't work out since Chanelle walked a few days after.

BB15- Danielle. 15 was already intolerable, but it was still a bit watchable until Danielle got evicted and really all we got after that was Helen's reign of terror which didn't really make pleasant television.

BB16- 4in4out evictions. While I thought Sam, Harry Amelia and Marc were worthy additions to the series, this stupid twist ruined the flow of what could have been a great series completely. Definitely the worst twist in BBUK history because it just didn't make sense and completely violated what Big Brother is supposed to be in the first place (a common theme that prevails throughout the series)
