CBB18 being awful has probably put people off CBB the same way BB15 did with BB during BB16.

I'll still hold out calling it a flop though. I remember most people were alarmed by CBB17's low figures during the launch and first week (especially when compared against CBB15's high figures the year before) yet the ratings slowly increased each week and were sometimes on par with CBB15's during the second half.
