The only thing scarier than seeing the monster is not seeing the monster, and Walter White never appears in the teaser for the last eight episodes of Breaking Bad. Instead,the clip shows time-lapse scenes of the New Mexico desert and familiar locales from the show, while Bryan Cranston recites Shelley'sfamous sonnet "Ozymandias"in a voice that grows crueler and more foreboding with each line. The poem isa requiem for a fallen, forgotten tyrant whose works proved less enduring than he thought they would a hint, perhaps, of things to come as Breaking Bad brings the story of Walter White to a close.The first of thefinal episodes premieres on August 11th.
