You have observed something very significant.

You cannot have good pizza if the crust is not good. No matter how good the sauce and cheese and toppings are, if the crust is not good, it will ruin the experience.

There's a pizza buffet chain called CiCi's Pizza in various cities in the US. I tried one once in the 1990s and tried one a thousand miles away two years ago, and it was the same: the crusts of the pizzas tasted like old stale bread that had been sitting on top of the refrigerator too long. They seem to buy their crusts pre-made and put toppings on them and throw them in the oven. They also seem to be buying the frozen crusts from the lowest bidder.

Just so, when a pizza sits in the refrigerator and gets old and cold, what's the most disturbing, wrong thing about it when you try to eat it cold the next day? The crust usually has hardened and turned into bread-flavored concrete. If you microwave it, and the crust softens, it will be edible again.

The crust is the fundamental foundation of the pizza. This is not to say that a good crust will allow you to use poor quality ingredients for the rest. Rather, it means that a bad crust means a bad pizza--a waste--and you cannot fix a bad crust by putting good toppings on it.
