"More folly has been written about the sonnets than about any other Shakespearean topic" was the judicious estimate of E. K. Chambers in 1930; there seems to be little reason to modify the statement now. 

--from Hallett Smith's introduction to the sonnets in The Riverside Shakespeare (1974)

News flash: Guess what? It's daunting to be a regular person who's trying write a book chapter about a Shakespeare sonnet. Why is it daunting? Well, because Shakespeare is a mountain. But that's okay: that's the challenge and the vision. The real problem is people like these snotty, patronizing English professors. Can't they find anything better to do than to frighten readers away from their own thoughts?
