First of all let me just say that this movie has the worst anticlimatical ending of all time: there's no verbal or telepathic communications established with the aliens, no sense of what their intentions are, no reason mentioned for why they've abducted people, no reason to explain why Richard Dreyfuss' character is the "chosen one", and worst of all we (the audience) are left to believe that a stupid little hand gesture means that everything is all hunky-dory with the aliens- case closed, everything is all right with the aliens because Steven Spielberg says so. Don't worry about cattle mutilations or any of those other violent abductions you've been hearing about, everything's all fine and dandy.
