I think that for such a campaign to work it should not be drawn out as nobody is gonna keep coming back every week to check if there are some vids and pics on that website...so I guess they are going to reach the end as soon as possible.
I understand why fans are finding this annoying. Rihanna stretched this era for too long, we're not used to this (she used to ****ing record a full album in two weeks EVERY year!) and now suddenly we have to wait for so long without any concrete information with speculations coming out every month / week. And now this. If this happened back in March, lets say, nobody would complain. But we have been teased too much and been turned down by false information for too long that the anticipation is gone and we're just left with bitterness.
I loved the teasers so much... I just wish they were longer. Like I wouldn't mind if it was all the same, Rihanna looking at the painted walls and in the bed with kids, but if only each room had a 3min+ video...
