These two touchstones of 70's cinema are far more arty and weird than expected and the underappreciated, divisive sequel is punishingly challenging. It's rare for any actor to shine as brightly as Gene Hackman but even rarer for a sequel to a multi-Oscar winning film to replace the director with someone equally exciting, going from William Friedkin to John Frankenheimer, both at their peaks. It maybe ground zero for the cynical modern cop drama but are as were as artistically dazzling as these films.
