I know many will disagree with this but truth is, Roma was the best thing that happened to VV and everything seemed to go downhill when he left. He was in charge of the parties, he was not shy about wanting sex from the girls, but more importantly he brought a different kind of energy that was unique to all the other voyeur apartments, which in turn made the house interesting to watch. A lot of that had to do with the living situation which was unique in itself (one couple and two other roommates) but everything seemed to center around whatever Roma was doing.
With this new couple, I don't personally find them all that boring but the problem is there is nothing that sets them apart from any of the other couples on RLC, so there's nothing special about them. Maybe another couple living there would help. Or at least a third person living there would help. But they need to set themselves apart and become unique again.
