ELI5: What is it about french fries in particular that make them nearly impossible to taste good once reheated in the microwave?

Microwaves cook by heating up water molecules inside your food. When the molecules warm up they are drawn to the surface and tend to make the food soggy on the outside and dry inside. That is the opposite of how you want french fries.  Try reheating french fries with an oven.  It will keep the outside cooked and the inside relatively moist.
