(Qualifier: the following opinion is based only on a few episodes.)
The show has the potential to be pretty good, but probably never will be because major networks are so dumb. They try to squeeze about 200 plots into each episode...to the point of being completely absurd.
The show has a fantastic cast, though, and it's pretty entertaining. I'm just not sure how long they can keep that pace up without either running out of material or just becoming bad.
