The last conversation between Leslie and Ben, in which Ben opens to box to reveal a "Knope 2012" pin, highlights one of Parks and Recreation's greatest assets. It can be dopey at times, with silly antics and behavior, but it can also be keenly self-aware of these characters and how great they are. The scene is heartbreaking and sweet, as Leslie moves forward in her professional life while leaving behind part of her personal life.
There was a substantial amount of plot development in the season premiere, with Andy hired as Leslie's assistant, Leslie officially running for office, and Tammy One's arrival. There wasn't enough time for funny things to happen, though the penis pictures and Ron Swanson were very funny. The episode sets up the plotlines for the season and I'm sure glad the show is back.
