I know there are a few threads on it but not for this purpose. I didn't watch it properly first time around and can't really remember it but I've just watched the first episode and hooked already. Its only 7 episodes long so not really a big commitment like the err ... successful (?) BB3 rewatch.
For those who don't know its a bit like BB but more competitive, and based around sleep deprivation.
Anyone interested in watching it again? Use the thread to discuss if you do
