Depending on individuals' feelings on Zooey Deschanel, everyone is going to have a different opinion about New Girl, because she's basically the show. There are a couple more characters to round out the ensemble, but they just more people for Jessica to interact with and show off her quirkiness. Personally I can stand large doses of her and had no problem accepting all the weird things her character does. I found her funny and liked the insanity which makes guys stay away.
The problem with the pilot, however, is that there is nothing to fall back on after Jessica. The other characters seem fine, but they don't immediately offer anything of value. And Coach, one of the flashier of "the Others," won't be on the show since Damon Wayans, Jr is going back to Happy Endings.
We'll see how the show develops in later episodes. Maybe Zooey Deschanel can sustain a show by herself and maybe not. There are still many unknowns, so I won't cast judgment on the entire show just yet.
Score: 8.3/10
