This show has been one of the best shows I ever watched. Raymond Reddington teaches you about connecting the dots to see the bigger picture. No information is useful and it will surely find use at just the right time.
His monologues were surely one of the best and his brain signifies why he is called the concierge of crime. He can outmaneuver every impossible task.
The value Raymond places on the people he loves is indeed the pinnacle of undying loyalty to him. His relationship with Dembe is very beautiful and signifies one of the most beautiful relationship between men on screen.
