Honestly, not enough. I have a habit with the C5 series of getting bored halfway through or 3/4 in, and I've been watching the older series over time so I'm not finished with any yet.

I feel like I've seen a LOT of the show through youtube montages, clips, and best bits.

Every single one, since I was 10 years old.

I started watching Big Brother around halfway through BB14 (just after Dan's eviction, I think) as I was staying at my cousin's for a week and just would watch it with them. Then I got hooked and carried on watching at home.

BB15,16,17 and CBB12,14,15,16,17,19,20,22 are the ones I watched in full, live.

I watched BB8 on YouTube a couple of years ago, too.
