In internet culture, the worst is merely not the best. Look out there and you'll see far more 1 and 10 star reviews than logic can really uphold. For Superman, the existence of Grounded creates that vivid 1 star reference.
I hope they'll be moving to metropolis here, but that won't be the end of the slice of life stories they seem to enjoy telling. Unfortunately, that means every other storyline is going to be called "Grounded," the story so bad its own writer left. Or "worse than Grounded, " as in worse than a long story only assuaged by a total reboot.
