THE KARATE KID

The opening scenes in director Harald Zwart's The Karate Kid remake, with the preternaturally confident and magnetic Jaden Smith taking over the Ralph Macchio role, are really good. But your first indication that the movie might wind up being really great - or, at the very least, a really great time - comes with its introduction of Mr. Han, the Pat Morita substitute played here by Jackie Chan.

WHIP IT

In case you hadn't heard, the coming-of-age comedy Whip It marks the directorial debut of Drew Barrymore, and it's an ideal project in a Baby's First Directing Gig way; the film is exactly the kind of earnest, peppy, relentlessly formulaic Hollywood outing in which a novice helmer can get her feet wet without causing too much damage. The surprise of the movie, though, is that it's so enjoyable, especially considering that so far as its storyline goes, nothing in it is the least bit surprising.

NEVER BACK DOWN

Watching the so-silly-it's-almost-fun mixed-martial-arts melodrama Never Back Down, I felt instantly transported to the summer of 1984, when my friends and I saw The Karate Kid the first time around. Fight Club was still 15 years away, so we weren't yet treated to this film's bone-crunchingly "kinetic" violence, nor to the sight of shirtless brawlers pummeling each other with their pants buttoned 12 inches below their navels. (Nor, for that matter, to topless teenage lesbians making out in a jacuzzi.) But Never Back Down is still pretty much Karate Kid redux, and the experience of watching it felt like time-travel for another reason: The movie's high-schooler lead is played by Tom Cruise.

METALLICA: SOME KIND OF MONSTER

Metallica: Some Kind of Monster has the sort of title guaranteed to repel viewers who might love it the most. This warts-and-all documentary, chronicling the two-plus years devoted to creating Metallica's St. Anger CD, is like the best episode of Behind the Music ever made, offering an intimate look at the relationship between guitarist James Hetfield and drummer Lars Ulrich, and detailing the nightmare involved in getting the group recording again after a five-year hiatus. The movie will be Mecca for metal fans, yet its appeal isn't totally insular. Audiences who may be loath to sit through a doc on any heavy-metal group might not realize what directors Joe Berlinger and Bruce Sinofsky have fashioned here; Some Kind of Monster is one of the finest recordings of the collaborative artistic process ever committed to film, a hard-edged and endlessly fascinating look at the excruciating work that goes into the making of an album. And for those for whom documentaries are even less appealing than heavy metal, it must be said that the film is one of the funniest and most shockingly touching screen works of the year, This Is Spinal Tap with actual human beings at its core. It's a thrilling experience.
