This year, the nominations had a minimum of three people facing the public vote each week, whereas previous series had a minimum of two. Which do people prefer?

I much prefer the old way of doing it. With a minimum of three, the majority of people nominated were generally up for eviction. When it was two or more, one nomination was more likely to completely change it. I like it when it's less predictable.

I much prefer the 3 or more. Gives you more of a fair choice imo

I like a minimum of three - helps stop a voting bloc from forming.

3 or more definitely. Luke A vs Lauren last year was horrible, and we would have had the same thing this year with Gina vs Dexter.
