KFC has gone down the crapper quality wise. As a kid, when my folks would get a bucket of KFC for us to have in the station wagon at the drive-in movies, it was a special treat. When my kids were young in the mid to late 90s, it was still really good. Since then it’s turned into a tasteless shadow of its former greatness. And their potatoes and gravy - which used to be addictingly delicious - is horrible pasty glop now.
It was just regular fried chicken with a somewhat unique flavor, pretty solid for something to grab fast. Now it's just loaded with salt and they're constantly "inventing" gross combinations of their sides and chicken. KFC and Pizza Hut really are prime case studies for Idiocracy, their offerings in other countries are even weirder sometimes. What is wrong with basic fried chicken and pizza? There's no need to improve.
