Now in its third season, watching my beloved Upper East Siders trade partners every three episodes isn't nearly as exciting as it was when they were in high school. The show is severely lacking in focus and the characters are losing redeeming qualities by the minute. Not to mention it's (gasp!) kinda boring.
My suggestion: Introduce some quality fresh meat (not always evil characters), and develop the story lines a little bit more instead of plowing through them in two episodes.
