I'd say the mainly obvious ones are

BB8: Charley's eviction (although I still think the Halfway House week was pretty good)
BB15: Toya's eviction
BB16: 4 In 4 Out eviction

You could probably argue that Narinder's (BB2) and Heaven's (BB12) evictions were turning points too.

When they revealed the 4in4out twist was the moment I knew the series was gonna be even more ****ed up than the last. And they continually proved me right

BB7: HND/Nikki's eviction - the rot set in as early as Grace's eviction though
BB8: Charley's evicted
BB11: When the lesbians left, I forgot their names I haven't watched it since 2010
BB14: Idk if everyone would agree but it got boring for me after Jackie's eviction?
BB15: Toya's eviction
BB16: 4 in 4 out
BB17: Charlie's eviction

[Jake.]

BB8: Charley's eviction
BB9: Around Bex's eviction onwards (not saying she was missed, just was around the time things changed)
BB11: Sunshine's eviction
BB14: Around Jackie's eviction onwards
BB15: Danielle's eviction
BB16: 4 in 4 out

[VanessaFeltz.]

BB11 Caoimhe and Shabby leaving

[TomC]

BB11 for me was Shabby leaving.

BB15 was Toya's eviction.

[Ashley.]

BB7: House Next Door
BB8: Halfway House
BB9: Rex's girlfriend
BB11: New housemates
BB16: 4 In 4 Out

I don't think BB6 and BB13 had decline points.

[Daniel.]

BB7: HND
BB8: Charley
BB15: Toya

I preferred 16 diring the money week, the furst two weeks were boring.

Why is everybody so passionate with Toya? She wasn't that good, she said more things than she actually did...

I agree, Weeks 9 and 10 were the best of BB10. It dragged a bit before then.

[Marsh.]

Wow, Toya is overrated.

[Lostie!]

BB11: Week 5 onwards. Sunshine's eviction pissed me off but Week 4 ended up being my favourite week of the series funnily.

BB15: Week 4 onwards. Not because Toya left though (her going annoyed me because I wanted Ash gone, not because she was a great HM in her own right because she wasn't, she had one good week preceded by two awful ones).

BB16: 4 In, 4 Out onwards.

Lmao this made me scream for some reason

[Greg!]

The decline point for BB15 was when Helen was given a pass to the final on Day 2. One of the worst ideas they've ever had

[VanessaFeltz.]

Sunshine's eviction made me sad but she had to go to keep my lesbians safe <33

BB1 - Nick getting clocked and Nichola leaving in the same week.
BB2 - Amma getting the boot
BB3 - Never
BB4 - on launch when anoushka was evicted
BB5 - after victor left
BB6 - Never
BB7 - unwatchable when nikki left
BB8 - After Charley's eviction but like hayden said the halfway house was still a tad entertaining.
BB9 - when the rich/poor divide happened.
BB10 - Karly leaving
BB11 - started falling after sunshine left but completely dropped when ben was evicted - also the focus on jj and josy was the main reason it was a bore.
BB12 - Jem leaving
BB13 - Never
BB14 - after the safe house.
BB15 - after toya left
BB16 - 4in4out
