CBB9: Everything about it was perfect. Karissa and Kristina are the greatest CBB Housemates of all time

And as much as I hated Denise, she was a hilarious trainwreck and deserved to win. There are so many memorable moments.. Pantsgate, Kirk and Natalie's shock evictions, the twins making the final, Georgia v Kirk, Michael v Denise.
BB12: A house full of boring 18-30 year old models doesn't interest me. The Pamela twist was stupid. There were too many houseguests. The goddess Heaven being evicted over Aden was the final straw for me and I stopped watching.
BB13: Despite their promises C5 once again gave us a house full of boring 18-30 year olds. All of the good housemates were evicted within a month. The crowd is more annoying than ever, booing literally anything that moves and ruining the eviction interviews. There is a very nasty, depressing feel to the house which I don't find entertaining at all. I stopped watching a couple weeks ago.
CBB8: Nothing memorable happened, there was only one round of nominations, the winner was a misogynistic douche... Probably the worst CBB of all time.
