I think Romeo and Juliet's love is shallow. He meets her for the first time in Act 1, Scene 5, then he kisses her within the first few sentences. TWICE. This shows that he loves her simply for the way she looks. We know he doesn't love her for her money or family because the families are rivals and his family is wealthy too (though he doesn't know who she is until after the kisses). He has spoken to her ONCE IN HIS WHOLE LIFE then falls in love and kisses her. He doesn't know anything about her to make him love her though, all he knows is what she looks like. This is very shallow.
