I haven't been this impressed with American cop series since Life. I sincerely hope that this one last longer than just two series.
The story lines are eppic and getting better all the time :) Although I have only watched a couple of episodes so far I am so hooked.
I don't think the story line is as painfully predicable as other shows I have watched in the past; Nor is it as actioned packed as 24... But then again, 24 would be difficult to beat in that respect!
The characters' are interesting and dynamic and I like the cast so far.
