Romeo & Juliet - Love at First Sight

I do not believe in love at first sight. For example, in this movie Romeo crashes the Capulets party and spots Juliet prancing around in a robe dress. Then he starts going off about how he never felt so much love at that very moment. This makes me furious. He just saw her this makes no sense to me he does not even know her name at this point, and he is already confessing his love. I understand that this is a story and in some cases this just might happen, but come on! Furthermore in the story Romeo decides to boogie down on the dance floor with the rest of the crowd and just so happens that his dancing partner becomes the one and only Juliet. Then this character that has nothing to do with the plot comes on screen singing for hours. Then all the sudden the two "meant" two start searching for each other in the crowd jumping and knocking over people. Then they found each other and he grabbed her hand and she pulled away! Then they start having a conversation about sinning. Then they kiss! They just said that in touching of the flesh and caressing of each other was a sin, THEN THEY KISS! What goes on in Shakespeare's head beats me but this just does not happen . I can't express how much This story really irritates me.
