I had a lawyer once tell me "It's not about the facts but about how they are interpreted and how they are delivered to make them believable." I learned that every great case has many possible twists in which a lawyer can try to make a good argument to defend a case. Hamlet would be among the best cases of them all. Even though it's a nice story and pretty straight forward, it is one of the best demonstrations of how ideas can be manipulated.
Now, Von Schlegel wrote an essay where he generally just states the things that happen that people might interpret in several ways. For instance, the idea of Hamlet longing to be king is often argued as being a crazy thought or just human nature to want more. But he goes far enough to mention that Hamlet kills his uncle and that it can still be argued as not insane.
Some things just can't be argued against. Hamlet is a tragedy and will remain that way. However, people add comedy into it all the time. Schlegel thinks of Hamlet with Ophelia as either a fake love, or just some temporary affair. It's all up to the reader. But there are other things fixed like the idea of the corrupt ones put behind bars and the ghost of his father being there to help.
To conclude, there are some things that just must remain the same and others that can be seen as complete opposites of what they really are.
