How does this Shakespeare text appeal to a 21st century audience?Such as values/themes, techniques and characterisation Romeo and Juliet by William...

Indubitably, the beauty of the language of Shakespeare's
Romeo and Juliet is unsurpassed by any others written by the
Bard as the entire play is a poem.  As such, the verse is so poetic and lovely that
audiences throughout time have enjoyed its beautiful expression of human passion and
love that is eternally fresh and creative. Who cannot cite passages endeared to them
such as the following expression of courtly love by Romeo who is so enamored of Juliet
that he would delight in simply being a glove upon her lovely
hand:

See how
she leans her cheek upon her hand!

Oh, that I were a glove
upon that hand,

That I might touch that
cheek! 

Added to this
enjoyment of the poetic beauty of Romeo and Juliet is the natural
inclination of readers to enjoy a love story.  Certainly, many a younger reader delights
in the romanticism of this drama in which an impassioned Romeo and Juliet love each
other so much that they are willing to forsake their own names in order to marry each
other.  Likewise, the older reader, too, delights in the impassioned characterization of
the young lovers, perhaps recalling his or her own youth that felt much the same
exuberance of emotion.  Indeed, it is the idealization of love that so enthralls readers
and its splendidly poetic expression that delights them, no matter what the
age.
