With respect for "Ozymandias", "Face Off", "Full Measure" and "Felina", this episode represent represents the essence of Breaking Bad. There is no better scene on TV than the end of "Crawl Space": the sound, the camera movement, Cranston's performance, the feeling of not knowing what will happen next and the black screen with "Created by Vince Gilligan". The result of the perfect construction of an episode.
