The show makes a lot more sense if you assume every character you see is a murdering sociopath. Whoever you assume is the good guy ... Sociopath. Ah but how about that bad guy who might actually be a good guy.... sociopath. How about the character who seems very complex but you don't know what he/she is really about? Also a sociopath.
The lot of them: Grandiose visions and schemes while killing others without remorse.
Makes me really wonder about the writers on this show. Heck somebody might want to look into their past to see how many "accidental" deaths have happened in their proximity in their lifetime.
3 star on scale of 3 star being the average show on NBC. I suppose on an absolute scale I would give it 2.
