Ensemble Dark Horse: Martin and Belle. Martin for his great Character Development into the competent and level-headed voice of reason of the group, and Belle for her memorable swimming scene where she saves Reverend Scott's life.
Funny Moments: Early on, Robin fights with Susan and says "Shove it!". Susan tells him never to talk like that to her, prompting him to say "Shove it shove it shove it!".
Incest Subtext: Nonnie seems really close to a guy in the band, stroking his face while singing a love song to him. When he dies she similarly strokes his face and is inconsolable. Then we find out he's her brother.
Special Effect Failure: You can clearly see that the rope Belle follows in her big rescue scene is securely attached to the set at several points.
Tear Jerker: After Mrs. Rosen dies, her husband refuses to leave her side.
That and the fact that Belle died before she even had a chance to meet her grandson.
Mrs. Rogo's death, which causes her husband to break down in tears and fall into a deep depression.
The 2005 TV movie:
What an Idiot!: The Cruise Director, who gives away Rogo's purpose as a sea marshal, and insists that everyone stay inside the dining room, even after it's pointed out that the ship will inevitably sink.
What Do You Mean, It's Not Symbolic?: Near the end of the film, the survivors have to cross over a pit of fire via a narrow bridge. The only ones who don't make it are Badawi, who masterminded the terrorist plot, and Shoshanna, who was Richard's mistress.
The original novel:
Harsher in Hindsight: A tsunami that kills a lot of people on Boxing Day? Needless to say, it's even more horrifying after 2004...
Values Dissonance: The whole "Susan getting raped" subplot, full stop. Not only is the attack itself completely superfluous to the plot, but her subsequent reaction to it (she sympathizes with her attacker, to the point of mourning his death, planning to meet his parents after getting rescued, and hoping she's carrying his rape-child) could only be the product of a male author from a pre-feminist generation.
