The Landscape​

Difficulty in recognizing what depends on what is the main reason why the code is unreadable. It applies to both: a micro and macro scale. It's this relationship that makes the fabric of a mental model.

Frameworks solve this problem by forcing a specific structure on the code. This is what developers like because code becomes predictable. When the dependency model is easier to read, the logic is easier to follow. However, in my opinion, popular frameworks are doing way too much in this department. Everything is clean on the surface level but ugly underneath. And if things don't quite work as expected because of the hidden framework's logic that you didn't fully grasp, you are in for a rough ride of debugging a framework instead of your own code.
