Looks to me like the show has devolved into being less interested in fashion and how it's created and more interested in causing tension, drama, in-fighting, etc.
TPTB: "Wait, we have only five designers. They all work reasonably well together at this point. No one's fighting! No one's stabbing someone else in the back! All we see is designers designing, creating...where's the audience appeal in that? No one wants to see the creative process... They want drama! They want Big Brother! They want Real World! Quick, bring back Angela and Vincent!"
