I'd say BB1 is hugely underrated, it's a much simpler kind of show but personally I love it. There's some great housemates, all of the interaction/drama is natural, no producer manipulation, and it stands alone as being the only series where the housemates had no idea what to expect. There's also more excitement to the live eviction shows because it was all so new and obviously such an unexpected success at the time and seeing that build week after week, I mean starting the finale with Davina in a helicopter... when will Emma?
I love it.
