Many people will claim that Shakespeare is perhaps too effete or pretentious, and while the language (which is actually recent enough to be Modern English and not actually Old English despite what many think) is very archaic to modern ears, and requires contextual help to fully understand and appreciate, the actual stories and the themes presented in them are very grounded and timeless. Here, Hamlet is struggling with suicidal thoughts of death and by skillful use of metaphor, Shakespeare eloquently portrays the dilemma presented before Hamlet facing his seemingly insurmountable problems. The way Shakespeare so expertly portrays Hamlet's increasingly pervasive melancholy decent into despair is timeless and universal.
Just a heads up to anyone who might care, Akira Kurosawa's various film adaptations of Shakespeare are fantastic if you don't care for the Early Modern English, and they beautifully illustrate how the themes of Shakespeare are universal and timeless.
