Though creator Erik Kripke originally planned for "Supernatural" to run only five seasons, its sixth proved to be just as well scripted and executed. The Blu-ray, with its fine audio and video quality and sizable set of extras, maintains the high quality and consistency of past season releases. Supernatural: The Complete Sixth Season Release Date: Available now Studio: Warner Home Video Packaging/Materials: Four-disc Blu-ray case with slipcover Year: 2010-2011 Rating: NR Running Time: 22 episodes, ~15 hours MSRP: $59.96 THE EPISODES SPECIAL FEATURES Video 1080p high definition 1.78:1 High definition Audio DTS-HD Master Audio: English 5.1 / Dolby Digital: Portuguese 2.0 Variable Subtitles English SDH, French, Dutch, Spanish, Portuguese, Variable The Season: 4.5/5 It's been a year since the chapter-closing events of the fifth season, in which Sam (Jared Padalecki) threw himself, the archangel Michael and Lucifer into "the Cage," effectively putting a stop to Armageddon. In that time Dean (Jensen Ackles) has settled down with his girlfriend Lisa (Cindy Sampson) and her son Ben (Nicholas Ella), and has given up the hunter lifestyle for a regular job and existence. But then Sam unexpectedly returns, just in time to save Dean from the poisonous influence of a band of Jinn looking for revenge, and though it seems like a genuine wish fulfilled, Sam's reappearance leads to some obvious questions. The most difficult to comprehend of the answers is that Sam has been back for as long as Dean believed him lost, demon hunting, of all things, with their grandfather Samuel (Mitch Pileggi) and his crew of distant relations. Though Dean initially resists the call back to the life he gave up, circumstances - namely the upending of the natural order of the demon world thanks to the unprecedented events of last year - force him back. Soon enough Dean's life of 9-to-5 normalcy is but a distant memory as the team goes on the hunt, specifically for an "alpha" vampire that seems to hold a connection to something much older and more powerful. Samuel in particular seems to show an unusual interest in tracking the creature down, though it's Sam's uncharacteristic behavior that gives Dean the most pause. From a more aggressive mien to an uncommon coldness, the Sam who's returned from Hell is clearly not the same Sam who went there. The angel Castiel (Misha Collins) could provide some insight into the mystery, but there's civil war brewing in Heaven with the loss of Michael's leadership, and their old ally seems to have little time for the concerns of mortal humans. Nevertheless, the Winchesters have been fighting the good fight long enough that they will undoubtedly help shape things in both the heaven and the hell that is to come. The fact that creator Eric Kripke only planned on "Supernatural" lasting five seasons meant its somewhat unexpected sixth could have fallen victim to a lack of direction. The transition of longtime writer Sera Gamble to showrunner could have been more fuel to the fire, but the series continued as it always had, with compelling character development, powerful story arcs, and some truly outstanding standalone episodes (e.g. "Weekend at Bobby's" and "The French Mistake"). The seamless transition from one "big bad" to another, ultimately leading to the most unexpected - and even heartbreaking - development of all, was incredibly well-charted. So much so that even after six years of the Winchester Boys chasing the supernatural, there's not much that's obvious leading into the seventh season. Like the hunter life it depicts, the series has proved to be anything but predictable. "Supernatural: The Complete Sixth Season" on Blu-ray includes all 22 episodes that aired on the WB Network from 2010 to 2011. The seventh season is scheduled to air on Friday September 23, 2011 at 9/8c. Video Quality: 4.5/5 The series is accurately framed at 1.78:1 and presented in 1080p with the AVC codec. Contrast is noticeably stylized, with crushed blacks and sometimes blown out highlights, creating a stark, high contrast image that suits the dark and sometimes gruesome material. As a result, black levels are consistently deep and inky, though shadow detail is often lacking. Fine object detail is excellent, particularly in skin and hair textures, and grain structure appears intact with minimal signs of reduction. There are moments of posterizing in background areas, but they are momentary and visible only under close scrutiny. Overall "Supernatural" has a great looking image that improves on its original high definition broadcast and most certainly its DVD counterpart. Audio Quality: 4/5 Past seasons were presented in lossy (though relatively high bitrate) Dolby Digital 5.1 audio, but the sixth season now gets a lossless track. I can't say there's a dramatic improvement with the switch, but the change is appreciated on sheer principle. Dialogue is consistently crisp, clear and intelligible. Support for the score in the surround channels is balanced and seamless, as are the sometimes aggressive atmospheric and directional effects. LFE is deep and robust, though - like the surround activity - somewhat measured in its application. Special Features: 5/5 The extras are spread across all four discs, though the bulk of them can be found on Disc Four in the "Hunter's Guide" interactive feature. Covering a wide range of topics and a variety of materials on every episode, the piece alone would be considered thorough, but the addition of two solid audio commentaries, additional behind-the-scenes pieces, and a hilarious gag reel make for an excellent all around package. Episode Booklet: Includes descriptions, original air dates, and writer and director information for each episode. [Disc One] Jensen Ackles: A Director's Journey (26:46, HD): Chronicles, through detailed behind-the-scenes footage and interviews, the process and challenges behind Ackles's first directing gig, the humorous and deconstructive "Weekend at Bobby's." [Disc Two] "Clap Your Hands if You Believe" Commentary: Sera Gamble, Robert Singer and Ben Edlund provide a detailed background behind the writing and production of the season's ninth episode, a clever homage to "X-Files." Gaps of silence are rare, though the jokey atmosphere sometimes moves things off-task; overall though the information is interesting and the group shares some amusing anecdotes. [Disc Three] "The French Mistake" Commentary: Sera Gamble, Robert Singer and Ben Edlund provide a detailed background behind the writing and production of the tongue-in-cheek, alternate reality fifteenth episode. "The French Mistake" Trivia: Pop-up trivia track runs through the length of the episode and offers additional information around the production of the show, with tidbits around what's real and what's been embellished for dramatic purposes. "The French Mistake" Alternate Takes and Outtakes (4:28, HD): Most of the material comes from the hilarious sequence where the two main characters are trying to act. Episodes from Supernatural: The Anime Series: Sample episodes give a taste of the anime version of the series, originally created for Japanese television. The selections are smart ones as they show how the treatment draws from the series, remaking the final two episodes from the second season, but also puts its own spin on things.
