I'm sorry, I hate to come across as a snob here, but Shakespeare is not that hard to understand.
If you watch the movie (or play or whatever) even if you have trouble at first understanding it the general idea of it should be clear to you based on what's going on in the scene.
Well, to each their own. If I wanted to try to figure out a story with no dialog, I'd watch a silent film. At least then I wouldn't have to hear people attempt to speak in a language both close enough to and far enough away from modern English to be annoying.. Actually, I have seen a silent film and liked it, so that's got Shakespeare beat. Shakespeare did not write in modern English.
Heck, he didn't even write in a language anything like modern english. There are some identifiable english words in it, but its practically nonsense. It makes sense that its written like this because its ancient. But to never translate his dialog after however many centuries just makes his work strictly for, well, Shakespeare snobs. Seriously, I tried to challenge myself to try to read a Shakespeare play a few months ago. I got exactly as far as the second page of MacBeth, and my brain melted out of my ears. Now, I consider myself a good reader, I read a lot and often, but I might as well have been trying to read a book written in French.
