I was first introduced to Shakespeare some time ago in school, when my English teacher allowed us to decide on whether to read Macbeth or Romeo & Juliet. I voted for Macbeth, but the majority wanted to delve deeper into R&J (which I enjoyed nonetheless), so I dismissed my initial hope to read this classic tragedy about the psychologial effects of tremendous political ambitions on those seeking power. I certainly don't regret having read it during the fast few days - it even made me want to read more of Shakespeare. 
 The path of Lady Macbeth and Macbeth into the realms of madness was perfectly executed, making it a 'must-read' for everyone. Shakespeare is a classic author who should be read at least once, and I've been convinced to read him more than twice by now. It's nearly impossible to write a review on this story with its plot being mostly known and its significance exceedingly famous, so there's nothing left to be said except for: "Read it!"
