Having just reread the story, I can assure you there’s not much there that could viably be staged. To their credit, the adaptors must have understood this. What they’ve created is something more easily staged: a love triangle. William is inexplicably in love with the consumptive Madeline, and inappropriately in love with the beautiful Annabel Lee. Now for the good bits: Madeline murders Annabel, Roderick obsesses, Madeline has a mad scene in a bloody dress, Annabel is trundled out as a Psycho-style corpse.
