I mean everyone knows the story of Hamlet so why retell it?
Exactly. Instead of just another boring retelling of Hamlet, I'd much rather someone do a sequel. Perhaps one in which Hamlet rises from the dead to prevent an invasion of Denmark led by Vlad "Dracula" Tepes.
Wouldn't you love to see Hamlet wading through a million-strong army of udead Romanians like a Cuisinart with dual broadswords. Wouldn't you love to see an epic duel between the Prince of Denmark and the King of Vampires, one in which their missed blows split mountains in half and create new rivers?
