I liked "Kryptonite" more than the pilot, despite the hasty addition of Winston, and think it shows far more promise than the pilot did. While the plot of the first episode basically revolved around Jessica being wacky at their place and the bar, "Kryptonite" tries to tackle an issue in her life, her ex-boyfriend. The confrontation with him was great and had all the comedic things down. After this episode, I'm on board and will be watching each week for sure.
Score: 8.8/10
