Having enjoyed its share of success with "The Blacklist" and various imitators, NBC treads similar terrain with "The Endgame," whose major wrinkle and upgrade involves casting Morena Baccarin (icily similar to her early "V" role) as a mysterious femme fatale. Slickly made and fast paced, it makes for an enjoyable thriller, although it's a dice roll as to how long that can last.
