Critical analysis involves analysis of CHARACTERS AND IDEAS.
Critical analysis in literature refers to the act of explaining a literary work in order to appropriately interpret it. This is usually done in order to enhance one's understanding of that work. A critical analyst can analyse either the characters or the ideas presented in the literary work.
An analyst can analyse a character in four different ways, which include the following: analyzing the words of the character, analyzing what the author says about the character, analyzing what other says about the character and by analyzing what other characters say about the character.
