It's hard to determine what makes a movie so good. Action, quotability, visually stunning? This movie has all of it. It's become a treasured piece of pop culture and cinema history and it is totally deserved. It's also an example of scifi at its best. It deals with themes such as; racism, classism, religious intolerance, war, animal rights, and science denial. Not bad for a film in which Charlton Heston yells at guys in monkey makeup.
