I'm just curious. I've never been a huge fan of this sideshow but did watch the occasional episode with Willis. Rylan is a massive switch-over for me. Any idea how it's rating?

300/400k

I see, and how does that fare against other series of bbots say during BB15 etc?

practically the same, the celeb bots gets about 900k

This year is around 400k, last year around the same maybe an average of 500k. I know that the January series did on average 800k-1m.
