Why is Shakespeare still being performed?

Is the nature of shakespeare's language to be elaborate because that would be the talent involved? In other words, is it more sophisticated to how people spoke back then?

Because his art is timeless, and some people still have taste even after all the brainwishing superhero movies.

I do.

Just because you don't like it or appreciate it doesn't mean it's bad.
Just because it doesn't come in text form or is explained to you doesn't make it bad.

I go to a Shakespeare event every summer.
I see about 5 or 6 plays every year.
It's an amazing experience to be brought to tears by a soliloquy with nothing but words.
No edits, no CG, no special effects, just true acting and dialogue.

If you can never appreciate it then I am sorry for your loss.

The power of every art is the openness of the audience to use their own imagination - their own interpretation, people dont like to be spoon fed, they want to find themselves in each art, that is the exact reason why for example Bible survived in relevace for so long, it's been written as sort of a poetry open to countless of interpretations, never to be taken literally. This realization alone helped me to start learning how to speak to people as the art itself, to be the art itself, conveying less clarity and giving everyone more space to interpret what I am saying. I am giving people the power back. Being vague, ambiguous carries great power, many people don't realize that this is how people used to speak thousands of years ago, it had a good reason.

I enjoy it immensely. Yes, reading it is tedious because it is difficult to understand. But when you go see it live, it is completely different. You then see the words as they were meant.
