Never liked Shakespeare much and Romeo and Juliet well was not much of a play I could get into. The posters that explained it do give a good translation I would think ? But not to sure. I recommend hamlet, if you need to learn Shakespeare
I suggest you watch Gnomeo and Juliet This scene in the movie is Juliet (the gnome) talking about how a color of a hat doesn't matter. So in the real book, it means why does her last name matter?
