I remember the original advertisement of KFC back in the days (at least in Asia) were 11 ingredients. Then later chemical analysis came out as 4 (salt, pepper, MSG, flour), with the main secrets being pressure fried.
I don't think the chicken they sell at today's US KFC is anything to brag about anymore. If you want fried chicken there are tons of better ones out there.
Now the KFC in a China airport, they sell soymilk and beef "pentagon" (think of it as a grilled stuff burrito from Taco Bell with no cheese and no rice, but beef that taste like a real taco), and that's awesome.
