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.

NIGHT AT THE MUSEUM: BATTLE OF THE SMITHSONIAN

Night at the Museum: Battle of the Smithsonian is to its precursor what Ghostbusters II is to Ghostbusters: the less-novel offering, sure, but a follow-up of surprising wit and great throwaway touches, and one that, in many ways, improves on source material that was pretty terrific to begin with. Despite its titular locale, no one is going to mistake director Shawn Levy's adventure comedy for a work of art, yet when this follow-up is really working - which is surprisingly often - it provides a giddy, giggly rush, and it's filled with comic bits that you could probably watch three or four times in succession and laugh at every single time. The movie is scrappy, silly, and a load of fun.

DRILLBIT TAYLOR

Last summer, when Superbad hit it big, we learned that co-writers Seth Rogen and Evan Goldberg wrote a first draft of the script when they were 13. Rogen is now credited as co-writer (with Kristofer Brown) for the revenge-of-the-nerds comedy Drillbit Taylor, and although I haven't done any research on the film's history, I'm kind of hoping it's something he began working on when he was, say, eight or nine. Juvenile is one thing, but remedial is quite another, and unfortunately, Drillbit Taylor feels as though it was hastily assembled during a grade-school sleepover in which Rogen began prepping Superbad, with My Bodyguard and Ferris Bueller's Day Off used as additional "inspiration."

HARRY POTTER & THE CHAMBER OF SECRETS

Although I didn't care for last year's Harry Potter & The Sorcerer's Stone, I was more than willing to greet the new Harry Potter & The Chamber of Secrets with an open mind.
