In his last completed role before his tragic death, Ledger is fantastic as the Joker, a volcanic, truly frightening force of evil. And he sets the tone of the movie: the world is a dark, dangerous place where there are no easy choices. Eckhart and Oldman also shine, but as good as Bale is, his character turns out rather bland in comparison (not uncommon for heroes facing more colorful villains). Director-cowriter Christopher Nolan (Memento) follows his critically acclaimedBatman Beginswith an even better sequel that sets itself apart from notable superhero movies likeSpider-Man 2andIron Manbecause of its sheer emotional impact and striking sense of realism--there are no suspension-of-disbelief superpowers here. At 152 minutes, it's a shade too long, and it's much too intense for kids. But for most movie fans--and not just superhero fans--The Dark Knightis a film for the ages.--David Horiuchi

On the Blu-ray disc
The Dark Knighton Blu-ray is a great home-theater showoff disc. The detail and colors are tremendous in both dark and bright scenes (the Gotham General scene is a great example of the latter), and the punishing Dolby TrueHD soundtrack makes the house rattle. (After giving us only Dolby 5.1 in a number of big Blu-ray releases this fall, Warner came through with Dolby TrueHD on this one.) One of the most interesting elements ofThe Dark Knightwas how certain scenes were shot in IMAX, and if you saw the movie in an IMAX theater the film's aspect ratio would suddenly change from standard 2.40:1 to a thrilling 1.43:1 that filled the screen six stories high. For the Blu-ray disc, director Christopher Nolan has somewhat re-created this experience by shifting his film from 2.40:1 aspect ratio (through most of the film) to 1.78:1 in the IMAX scenes. While the effect isn't as dramatic as it was in theaters, it's still an eye-catching experience to be watching the film on a widescreen TV with black bars at the top and bottom, then seeing the 1.78:1 scenes completely fill the screen. The main bonus feature on disc 1 is "Gotham Uncovered: The Creation of a Scene," which is 81 minutes of behind-the-scenes footage about the IMAX scenes, the Bat suit, Gotham Central, and others. You can watch the film and access these featurettes when the icon pops up, or you can simply watch them from the main menu. A welcome and unusual feature is that in addition to English, French, and Spanish audio and subtitles, there's an audio-described option that allows the sight-impaired to experience the film as well.

Disc 2 has two 45-minute documentaries on Bat-gadgets and on the psychology of Batman, both in high definition. They combine movie clips, talking heads, and comic-book panels, but aren't the kind of thing one needs to watch twice. More engaging are six eight-minute segments of Gotham Central, a faux-news program that gives some background to events in the movie, plus a variety of trailers, poster art, and more. The BD-Live component on disc 1 is more interesting than on some earlier Blu-ray discs, which could be simply a matter of the content starting to catch up with the technology. There are three new picture-in-picture commentaries, by Jerry Robinson (creator of the Joker), DC Comics president Paul Levitz, and Senator Patrick Leahy (D-Vt.--he's a Batman fan who's made some movie and TV cameos), plus you can record your own commentary and upload it for others to watch. There are also three new featurettes ("Sound of the Batpod," "Harvey Dent's Theme," and "Hans Zimmer and James Newton Howard") and two motion comics ("Mad Love," featuring Harley Quinn, and "The Shadow of Ra's Al Ghul"). No longer available is the digital copy of the film (compatible with iTunes and Windows Media, standard definition, download code expires 12/9/09).--David Horiuchi
