"“Alien 3" isn’t a classy, visionary nightmare like Ridley Scott’s 1979 “Alien” and it’s not really a hell-for-leather, super-tech toboggan ride like James Cameron’s 1986 “Aliens.” It has a different mood than either of its predecessors, and a different look: stylish but gloomy, portentously grim. It does succeed in rounding the three movies off, not smashingly but interestingly."
