It’s taken the Russian musical “Hipsters” four years to reach America. That’s all right. It may take audiences four years to recover. That’s how ridiculous and goofy and often maladroit Valery Todorovsky’s movie can be. It’s hard to say which is worse about the musical numbers: the music or the lyrics. That said, “Hipsters” is also kind of amazing, thanks to headlong enthusiasm and an endearing obliviousness to just how ghastly the whole thing keeps threatening to become.
