Literary Analysis is "the mainly interpretive (versus evaluative) work written by readers of literary texts, especially professional ones (who are thus known as literary critics).
It is "criticism" not because it is negative or corrective but rather because those who write criticism ask probing, analytical, "critical" questions about the works they read".
