In the poison'd entrails throw.
Toad, that under cold stone
Days and nights has thirty-one
Swelter'd venom sleeping got,
Boil thou first i' the charmed pot.
Macbeth, for all that it is and was entertainment asks some very big questions about fate and freewill. The creeping terror of the main characters being driven mad by their greed driven actions could very well push any movie made on it well into the horror category. It inspired Tolkien in his creation of the Ents. Sitting down and reading the play might take some time but the world created here is well worth the effort. If you are a more visual type plays make excellent graphic novels and someone figured that out so you can indulge in a play on paper as well.
