I cannot stand the Baz Luhrmann 1996 adaptation of William Shakespeare's Romeo + Juliet. He should have called it MTV's R + J. It's a music video, not a movie. And certainly not a play.
First of all, Luhrmann modernizes the setting and characters but retains the Elizabethan dialogue. Why? It's silly. Why would gang bangers talk like this? Why do they say they have "swords" and wave around 9mmers? Preposterous!
Recent adaptations of O (Othello) and Hamlet (2000, starring Ethan Hawke) have modernized both the setting and language, which makes much more sense.
Secondly, the actors (except for Friar Lawrence and the Nurse) have very little acting experience, let alone Shakespearean voice training. Instead, they shout all their lines while music blares in the background. Shakespearean plays are meant to be heard; their iambic pentameter is like a song. It takes years of training and experience. The couple in Franco Zefirelli's 1968 version were much better trained.
