I have yet to see a show conclude and everyone be happy with the ending or with the length of time the show ran...too long, too short, etc.

For me I couldnt get enough of the show but it had to come to an end and for a show to go "boom" for 10 seasons it made sense to go out with a "whisper". No high tech attack, no guns blazing, no "did he or didnt he die" type ending...Red was on his way out, dying, and knew it and went out as uniquely as he had lived. I will never not be a fan of the show or the character, Raymond Reddington. James Spader was absolutely magnificent in the role!
