Uwe Boll doesn't think his films are bad. He takes his craft very seriously and gets very upset if you question it. So does Michael Bay.
And yes, I want Shakespeare. Shakespeare is good, Michael Bay is bad. I would prefer good to bad.
But even Shakespeare wasn't Shakespeare in the way you're using the term. Shakespeare used characters and material that he didn't create. He wrote for a paycheck. He threw in plenty of blood and sex because he knew that's what the crowds wanted and because he knew that's how he would get his next gig. He wrote fart jokes.
But in all of that, he still wrote complex and human characters who were motivated by desires and took action based on those desires (or didn't, in the case of Hamlet). Their actions make sense, given what they want and the situation they find themselves in. The story progresses logically and consistently to communicate some kind of theme.
He was "Shakespeare" and Michael Bay at the same time. That's why he's William Fucking Shakespeare.
