Hamlet and King Lear are the plays.
Hamlet is the Lion King, with a bad ending, because Hamlet can neer make up his mind what to do, and when he acts in the end, it's too late, and everyone dies. Or strictly, the Lion King is Hamlet, disneyfied.
King Lear is even worse. Have a good leer at a king in trouble, loses his kingdom and goes mad.
When you understand who Hamlet is, or represents, then you understand also why the most famous line in it is so famous.
I only really got it when I was at Glastonbury in 1999, I came across this little tent selling cloths and so on from the far east,
It had a caption on a card outside, the name of the shop, kind of,
"To be or not to be, that is the question, artworks for the 21st century, or The scrap shop? "
And I looked at the cloths, and the artistry in them went on forever, honestly.
Oh, and they're good to read as well as see, btw., those two are.
