Slate: "The original high school musical is back!" crows the tagline on the poster for Grease Sing-A-Long (Paramount), a rerelease of the 1978 musical with karaoke-style subtitles. The jab at Disney's High School Musical series—and the grab for its audience—are as good-natured as they are blatant. In a summer of sequels and remakes and all manner of pop-culture pillage, you have to give Paramount respect: Rather than trying to "reboot" Grease for the new millennium, the company has simply dusted off the top-grossing musical of all time, slapped some words under the songs, and sent it back out on the market to reap whatever profit it can.
