That analysis part is key. The short answer is that criticism makes stupid people. Literary fiction provides words for experiences and memories, and when you apply a critical framework, it breaks the associations that the work of art was intended to create and substitutes in the ideology of the framework. This is why universities aren't producing writers. If you want to write well, read a lot, and then try to write something that you can look back the next day at without cringing. Teaching criticism is a substitute for that process, and mainly it makes people immune to good ideas.

The only criticism I think is worth teaching students is that they are being decieved and misled by their instructors and their job is to figure out how and why.
