Is typical American beer really that bad?

This is a serious question! Is the typical (no local breweries/IPA etc.) American light beer, like Budweiser, Coors or Miller that MANY Americans know and drink regularly actually as bad as it is presented?

I know there are probably many good breweries in America that a lot of folks wish to be more known.

But the run if the mill beer that gets a lot of shit even by your own citizens can’t be that bad if millions of people buy it everyday, right? Or is it just a question of demand and the price of alternatives?

I really want your input
