A show or movie based on a very simple premise or pitch is called a "high concept piece". This is a 13 episode anime entirely based on mocking a stupid quote by a nationalist Japanese politician. Sushi Police takes thin premise to a whole new level.
On the surface, this could be a clever, little satire that mocks the growing wave of Japanese nationalism and calls for rationality through comedy. However, this would have worked better as a 5 minute SNL sketch. At 13 episodes that are 3 minutes, this is 40 minutes of the same fucking joke done OVER and OVER until they pretty much forget the satire and make a Godzilla spoof because even the show writers realized they were trying to stretch too little material over too long a running time.
A defender of Sushi Police could point out that One Punch Man is beloved despite basically being the same joke over and over. However, One Punch Man actually had a massive art budget and fight scenes that aesthetically looked cool. It wasn't just, "I'm early, better think of a Superman...Superman! https://www.youtube.com/watch?v=jBLspvxgTdQ
