I generally don't mind "re-imagined" versions of Shakespeare, as long as they're well done. Romeo and Juliet with Mr. DiCaprio is not, btw in that catagory as far as I am concerned. Ethan Hawke did a version of Hamlet five or six years ago. Its cut down quite a bit, but it is very very good.
That being said, it makes me want to cry to know that so many people have no idea what these wonderful works were originally. *sigh*
