BB4 is I am afraid neither of the two options. It's not a conflict and neither is it nice. It's just boring.
BB is meant to be a spontaneous soap opera reality show. What soap opera is watchable if there is no conflict and the ability to see human emotions as they unfold. That's not the BB I understand. Such a soap would soon get the thumbs down from the majority and be removed from our screens
BB2 had the right mix with both conflict and love interest. BB3 went over the top with conflict but by george it's better than the flat and uneventful load of tosh that is being served up this year.
