Sheer delight. I suspect a lot of the appeal of this show is its wish fulfilment - we all want to act like Chloe sometimes in her snark and utter lack of inhibition. Also, she's such an amusingly (if horrifyingly) self-absorbed and charismatic character, so that the echoes of people one knows are all the more amusing (whether as actual momentary analogues or knowing assumers of the role or more likely a bit of both). And then there's the shininess in which it's all wrapped up - the usual televisual dream of NYC with the right amount of actual sharpness. Plus, James Van Der Beek makes an excellent James Van Der Beek.
