I got to visit Shakespeare's Globe in London when I was younger, and they did this lecture on the ins and outs of the play. How various actors didn't actually know their co-stars' lines until the night of the performance and much of the dialogue was informative ("What light through yonder window breaks? It is Juliet!" is Juliet's queue to step onto the balcony, for instance). How Shakespeare was constantly tweaking the writing (the guy who played Mercutio was such a scene-stealer that Shakespeare decided to deliberately killed him off halfway through the play after a few performances). How you had all this choreography, lighting, costume, and accompaniment that isn't properly documented in a high school reading of the play, and a great deal of how you deliver that is left to the producers.

Like, these are rarely ever good reads. They're functionally screenplays. Going through Shakespeare as written is like picking up a line-reading of Love Actually or Diehard, then trying to make sense of it without having ever seen Bruce Willis or Hugh Grant, knowing what New York or London look like, or having any idea how a 90s-era Westerner might behave.

You really do need to see these performed to appreciate them. And that, I think, is what makes a movie like this so good.
