Spent some money, experienced some inconvenience, felt like a fool. That's not "burnt real bad."
They lost thousands of dollars each, got taken for a ride to nowhere and were conned with nothing to show for it, not even a t-shirt. If that's not "burnt real bad", I don't know what is.
It's no small irony that the name of this non-festival that was hyped and then cancelled before it even started, was named "Fyre".
Burnt in the Fyre real bad, I'd say.
