Idk I could not even finish the first episode. Truly bad. Can you just like give me an episode to start at where it isn't terrible anymore?
I've watched enough sit-coms to know that the pilots, sometimes even the first seasons, tend to be pretty messy before the show finds its feet. How much genius do you find in the first season of Seinfeld? The Friends pilot? US Office pilot? Hell, even the first Parks & Recreation season was pretty patchy, and that show got really good from the second season onwards.
New Girl, at its best, rivals the great sit-coms of years gone by. Like others have said, it is pretty hit and miss, but I don't think the lows are all that bad. What I do think is one of its best qualities, and what makes me think of Friends, is the chemistry between the characters. Great comic timing, too, especially from Max Greenfield and Jake Johnson.
But yeah, the first season is mandatory watching to get many of the later plot points. It also has many of the show's best moments.
