NBC’sSuperstore isn’t just another workplace comedy. Creator Justin Spitzer found the last remaining piece of interesting real estate in this sitcom sub-genre and firmly planted the flag of fictional big-box Cloud 9 right in the center of it. This slice-of-life comedy features an age and culturally diverse cast full of entertaining characters that each bring their own thing to the table. Besides that, it has created and repeatedly followed a narrative thread of focusing on stories of personal relationships that are enhanced by exciting high notes of major events. Besides the Olympics-themed store fire, the helicopter, the black out, Cheyenne (Nichole Bloom) giving birth and the episode in which Marcus (Jon Barinholtz) cut his thumb off, the most recent event has been Cheyenne and Bo’s wedding – during which Store Manager Glenn (Mark McKinney) dropped the bomb that he has to fire six employees. In tonight’s season finale they have something even worse to worry about. Three guesses from the episode’s title: Tornado.
