I disagree completely that the plot is underdeveloped, and the characters might be somewhat cliché, but that's the idea. In my opinion this is what every story with a message does. It takes archetypes as representatives of all people in a society and shows their reactions, no one would say that Breakfast Club is clichéd because it plays with the archetypes to convey the message. And Superstore does the same, it shows prejudice, narrow-mindedness (from poor to educated and the other way round, both sides!!)wrongly understood sense of love or duty etc. etc., in short: all the topics that emerge between people at a workplace or in society and it does this very cleverly, very holistically and most of all: with a lot of great and refreshing humor -and without mocking its characters - great fun with sensitivity and a message, perfect entertainment, 10 points!
