Unfortunately, the opening 5 minutes was the high point of the series. I've seen the pilot in full and parts of other episodes, but just can't get sucked in to keep watching, and the critical reviews aren't exactly forcing me to give it another shot, to say the least. Most of the characters are self-important and self-righteous.
The rapid fire witty banter literally doesn't stop, ever (one of Sorkin's faults, as seen in The Social Network). The show has some good parts to it, but when I saw the previews, I was expecting much more than what we got.
