All you Need to Know about Romeo

Romeo played by Douglas Booth
in Carlei's Romeo and Juliet (2013)

He's charming, yet sweet with a childlike personality. All the girls in Verona swoon over his handsome features... but you would never guess he was a Montague unless you asked.

Romeo. Son of Montague. Male counterpart to Juliet.

Your first judgement of Romeo in Act 1 is that he is melancholy character whose main interest in life is love. This is probably because of his unrequited love towards Rosaline, but you can't blame him for this; the poor guy has been rejected by his only love. 

Romeo played by Leonard Whiting
in Zeffirelli's Romeo and Juliet
  (1968)

As the play moves on you realise he is in fact, a passionate and cheerful person due to his kindness towards Juliet. Upon meeting her, Romeo has a more positive view of life and openly expresses his thoughts more often. His inner feelings are expressed through his complex speech mostly containing metaphors and symbols about love. As all men are, Romeo's brave and daring nature is revealed when he decides to attend the Capulet's party regardless of the fact that he is from the rival family. After the ball, when visiting Juliet at Capulet's orchard after the ball, Shakespeare provides Romeo with a soliloquy which showcases the positive personality features he has.  Imagery such as metaphors "it is the east, Juliet is the east" and personification "arise, fair sun, and kill the envious moon" portrays Juliet's role as Romeo's love interest and represents Romeo's intelligence thorough the complexity of his speech.

But a person can never be perfect, as Romeo has a few downsides regarding his immaturity and impulsiveness. He relies on the guidance of Benvolio, Mercuitio and Friar Lawrence for support when in hard situations. These traits influence Romeo's hasty attitude towards life, and Shakespeare depicts this upon Romeo's first sighting of Juliet, the killing of Tybalt, and also his suicide at the end of the play. In Act 1 Scene 5 in lines 51-52 "Did my heart love till now? Forswear it, sight! For I ne'er saw true beauty till this night", this momentarily reveals Romeo's contradictory nature and highlights his impulsiveness, after his first sighting of Juliet as upon arriving at the ball he had loved Rosaline.

Romeo's personality is different to the one of Juliet, so by combining the two characters, it creates a loving couple
