21 Jump Street (R) ★★★☆☆
Heartily raunchy and rather sweet, this remake of the old Fox TV show, which starred a young Johnny Depp, actually brings the laughs. Real ones. In it, odd couple cops, Schmidt (Jonah Hill) and Jenko (Channing Tatum), go undercover as high school students to bring down a drug ring. But high school’s changed since the duo’s teenage days, and they struggle to relate to the modern cliques. The directors don’t try too much, and the script is clever and funny. Worth the ride.
