If KFC had found a way to include some more healthy options (or at least some less unhealthy ones) rather than doubling down on making increasingly more crazy unhealthy stuff (Cheetos Fried Chicken Sandwich, anyone?) they might have been doing a lot better.
All the KFC's in my area have closed down, and the one further from me back where I used to live had to move to a smaller, junkier, cheaper location. I know that KFC's mostly about fried chicken, which isn't bad, but I feel like they should have (and should still) diversify.
