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.
