Consider the following:
- Literary criticisms are not opinion pieces and often utilize other scholarship.
- They are not a substitute for reading the work and usually won't give overall summaries.
- Criticisms can be used as evidence to support arguments and help you focus your opinion.
- Scholars can provide other opinions and points of views you might not have considered.
Be careful not to overly rely on literary criticisms in your paper. Make sure you are still including your own opinions as well as relying on what can be drawn directly from the work itself.
