Brilliant.... but would never be published today!
Shakespeare's skill is to make his reader face up to awful situations, violence, macabre politics death and tragedy in a way that a modern publisher would never allow into print.
Despite the difficulty of the archaic prose, and the surreal world of medieval fiefdoms, the reader is compelled to face these situations with the principal character and forced to confront uncomfortable and disturbing issues that do not always have a "happy ending". The nearest modern equivalent might be something like Bob Berridge's "Mandy" (which only saw publication thanks to Kindle, and is similarly disturbing), but whereas the reader can more easily associate with Berridge's post war Yorkshire, Shakespeare has the task to port you into a world of petty kingdoms, royal power struggles and indeed issues of sanity itself and suicide. A task which, as the recognised master of his field he achieves with all the craft for which he is well and justifiably famed.
Don't read this book to pass an exam. Read this book because it is compelling and will make you think and challenge your comfortable beliefs. Despite its ending, a highly satisfying read!
