Don't most aspiring writers already do so, for some value of terrible? S.J. Perelman wrote a series of pieces, "Cloudland Revisited" about the books and movies that thrilled him when he was young but didn't stand up to later reading or viewing. Mark Twain's essay "Fenimore Cooper's Literary Offenses" is a classic, though on the other hand you might want to have a look at D.H. Lawrence and Yvor Winters on Cooper before giving up entirely.
