Compared to present disaster films, the theme and plot of this one seem quite naive. With time goes on, the stunts are not vibrating any more, and the plots are not attractive any more as well. Instead, the reality of characters become its merit. The actions of the people trapped in the endangered submarine laboratory were reasonable. They were not heroes so no one was eager to save the dangerous situation. Some of them were afraid of death, some were self-willed, some were desperate and feeble. The leaders weren't wise as well, so they didn't have much personal glamour. On the contraty, the rescuers showed 120% calm and bravery. It were the common characters and the plain actings that grabbed the sympathy of audience.
