The specific aspect of literary criticism that demonstrates the author's message as significant or worthwhile is the author-based approach. It is also called the Expressive Theory. It depicts that the best interpretation of a text (poem, novel, fictional stories, etc) comes from the author himself.
The reader-based approach is not entirely reliable because every reader may see a text in a different perspective. There are even cases wherein readers interpret a text in a deep, deep way while the author meant everything in the literal sense. Everything varies from case to case.
i say it is evaluation which was one of the answer in my question which is understandable since you evaluate the message of the author just like you evaluate if buying that candy bar was worth it, this is the main significant, was it worth it or not after analyzing it and interpreting.
