Although after Airport The Poseidon Adventure truly is the film that started the craze... The Towering Inferno, Earthquake, Airport 75 etc. all owe their getting made to this film...while Airport may have started the genre PS perfects it. Top of the line special effects, decent acting, and an edge of your seat story makes this the king of all disaster films. It's so good that no matter what I'm doing if I flip channels and hot this I stop and watch it.
