You're mostly right, but I disagree about the Shakespeare
You can plow through the text and get an exact meaning of the lines, but they are cumbersome and stilted. But in the mouths of skilled actors, with the visual and gestural cues and emotional emphasis, the dialog flows with the action and thought behind it and you totally forget its antique and stilted sound, not to mention that it is written in iambic pentameter. It sounds like real (and very interesting) people talking, just like it did to Elizabethan audiences four hundred years ago.
