If the show continues, they need a completely new cast. The familiar faces we know and love (lol) are simply way too familiar with each other now, as Chino said. There's nothing else they can do, and no where else they can go from here. This season was decent, but that spark that initially made the show interesting, is gone. Either start over or don't continue at all.
I will be watching the Pauly D Project though. Yeah buddy!
