Finished the entire season over a weekend and i guess it was worth it..
The acting specially of the lead roles is great, there's a new discovery every episode which always keeps you wanting for more. Ending too was a very thoughtful one which will definitely hook u up for the next season...
Having said all of this, there were definitely many realistic flaws. Mentioning few of them, like a guy is (spoiler alert) committing series of murders and no one is able to find out, like it's happening in New York , does the result of DNA sample takes months to come out. Peaches house and gun must be full of Joe's finger prints, can't the police figure even that out? And does every one in New York leaves their phone and laptop unlocked? And many more.
All that being said, I loved it only for acting and the overall story.
