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 acclaimed Batman Begins with an even better sequel that sets itself apart from notable superhero movies like Spider-Man 2 and Iron Man because 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 Knight is a film for the ages. --David Horiuchi
