In my opinion BB21 is a solid contender for worst pre-jury ever, it was boring and predictable imo. The jury phase however is a completely diffrent story, it started with the best HoH of the season, followed by a really heart-breaking eviction the week after, a complete blindside, then Nick's blowup and then one of the best double evictions we've seen in a while, my biggest issue was Jackson's domminance in the late-game though.
Jack is a solid cotender for my least favorite contestant, I shouldn't need to explain why.
I'd give it a solid 7/10
It had its ups and its downs, but I enjoyed it (for the most part).
