问答无用p In "Impulse" a female undercover cop (Russell) sting问答s johns, gets involved with a drug bust, and..问答.yada yada yada. A typical and ordi无用n无用ary Hollywood crime genre product with Russell and Fahey sharing the spotlight, "Impulse" is a par flick, shot entirely in and around L.A., with the usual ugly bad guys, macho问答 cops, chases, shootouts, etc. with the emphasis on drama over action. Nothing new here. Best enjoyed with your favoritpe beverage and munchies.
