Film Reviews: A "Jules and Jim"-like tale of two men in love with the same woman, "Where Have All the Flowers Gone" is at its best when it’s least hip. First feature by songwriter/commercials director Gao Xiaosong has the full battery of expressionist props and colors, pretentious dialogue and musicvid-style cutting and songs, but it’s the more natural moments that work. A curio for Sinophiles only.
