There is no objective true to claims such as "X is the greatest writer who ever lived". Even if you could objectively determine the best writer for a certain culture and context, there are countless other cultures and contexts. Is Shakespeare greater than Cervantes? Goethe? Dostoevsky? Who knows? Who cares?
The world is not only the anglo world. Other cultures have their own literary giants and you can bet that they value them more than they value Shakespeare.
When I have to force myself to enjoy something, I tend to wonder if the thing is really worth enjoying or if I am instead just trying to acquire a taste that I deem prestigious. To each their own.
