Trade Descriptions Act alert! John Travolta’s Chili Palmer wants to crack the music biz. So, he dances like your dad, uses a record company called NTL and comes up with the frankly unlikely idea that his Christina Milian-alike played by, um, Christina Milian, could rock out with Aerosmith. Irritatingly smug, this bland Get Shorty sequel is memorable only for The Rock’s gay minder and a smidgen of wit. Be Cool? It’s anything but.
