It did pretty badly with the viewer count so those 6 episodes are really just it.

P.S.: I can't believe New Girl is yet again renewed for another season.. like what the hell are they going to do different this time around, it'll just be dorky Jess with fake glasses trying to get together with Nick again. >_<
