AMC likes to boast that it is changing the way South Florida sees movies. This might just be true if the amount of time spent waiting in line for tickets could be dramatically reduced. Now comes AMC's automated box office machines at Aventura and Sunset Place. Could long box-office lines be a thing of the past? Take your credit card, slide it in, select a movie and time, grab the tickets, and run. Next stop: the concession stand. Is there something wrong with this picture? We hope not.
