I’m sure some of you out there are a bit bleary-eyed this morning after catching a midnight screening of The Dark Knight last night. For those of you waiting until today, or later, WORLD’s Sam Thielman’s offers his take on the latest Batman flick, including the much-talked-about portrayal of the Joker:

The film’s early reviews have been gently quizzical about the late, lamented Heath Ledger’s magnetic performance as the Joker. It’s obvious that he’s doing a superb job, but nobody seems to know what he’s doing. Let me clear things up: He’s playing Satan. Ledger flicks his tongue like a snake, tempts people to kill one another, and is gleefully sloppy with bullets, bombs, and knives. Everyone else plays gangland archetypes; Ledger’s Joker has escaped to the movies from Milton, or C.S. Lewis’ Perelandra.

Sam also offers this warning for parents:

I should note here that I have been a film reporter for years and have no idea why, beyond the power of the Warner Bros. empire, The Dark Knight is rated PG-13. This is an R-rated movie if I’ve ever seen one—the violence isn’t particularly bloody but it’s disturbing. You may laugh at the occasional demented gag, but if you do, you’ll feel ill. Don’t take your kids. They’ll whine about it. Don’t take them.
