One of the best episodes Supernatural has given to us so far, and the best episode of the season till now. In the end, we now have four dangerously powerful antagonists: Crowley, Rowena, The Family, and Metatron. Not to mention the sad angels in Lucifer's Pit and the Heavenly Angels. By doing this, Supernatural has set itself up for another four seasons at least. Now back to the episode, it was well-directed, well-balanced, and well-acted. For the first time, Charlie came out to be an important part of the show, instead of sticking out like a sore thumb. Dean was fun after a very long time. That beach question!!!! Sam's ordeal and emotions, which the show had constantly failed to highlight so far, came up this time, so powerful that his expression in the end reflected to the background music of The Who's Behind Blue Eyes (my favorite piece, and it fitted the theme as well). After a very long time, I saw Sam playing on emotions rather on righteousness, something he had been doing for quite some time. Now the antagonists. This episode introduced to the epic evil family, which keeps its hands muddied with sick magic. Book of the Damned is one of the diabolical things. The theme was great, and had a ring-Gollum vibe with Dean. Dean's acting made the book look more powerful and evil than the usual "gore" stuff. Though the pursuers went down in the end, it opened up a new door for the new villains for the show, someone non-heavenly or -hellish, chance for fresh air. The show definitely needs to come out of angel-demon wars and venture in new areas.
