I think Person of Interest
is pretty good. And although it started pretty slowly, The Americans
picked up nicely as it went on.
I only watched the pilot of Person of Interest. I didn't keep watching it because the protagonist struck me as 'Jack Shephard lite'. Maybe I"ll give it another chance.
I don't mind shows being episodic, so long as they have compelling characters and interesting writing. I loved House. Just, based on the pilot, Person of Interest only had one compelling character.
